What is cell biology?

Cellsform the basis of all living things. They are the smallest single unit of life, from the simplestbacteriato blue whales and giant redwood trees. Differences in the structure of cells and they way that they carry out their internal mechanisms form the basis of the first major divisions of life, into the three kingdoms of Archaea (ancient bacteria), Eubacteria (modern bacteria) andEukaryota(everything else, including us). An understanding of cells is therefore vital in any understanding of life itself.

Cell biologyis the study of cells and how they function, from the subcellular processes which keep them functioning, to the way that cells interact with other cells. Whilstmolecular biologyconcentrates largely on the molecules of life (largely thenucleic acidsandproteins), cell biology concerns itself with how these molecules are used by the cell to survive, reproduce and carry out normal cell functions.

In biomedical research,cell biologyis used to find out more about howcellsnormally work, and how disturbances in this normal function can result in disease. An understanding of these processes can lead totherapieswhich work by targeting the abnormal function.

The following list covers some of the more commonly used cell biology techniques it is by no means exhaustive.

Human Behavior

Human Behavior Psychology – Self Improvement

Human behavior psychology is one of the theories of learning based upon the central idea that all human behaviors are attained through conditioning. This is also known as behaviorism. Conditioning happens through the interaction of human beings with the environment. According to human behavior psychology, human behavior can be studied in a systematic, methodical, recognizable and observable manner with no deliberation of internal mental states.

The two major types of conditioning are:

Classical conditioning:

A common method applied in behavioral training in which a response is paired with a naturally occurring stimulus. Further, a previously neutral stimulus is paired with the naturally occurring stimulus. Eventually, the previously occurring neutral stimulus comes to suggest the response in the absence of the naturally occurring stimulus. The two elements are then known as the conditioned response and the conditioned stimulus.

Operant conditioning:

This is another frequent method of learning that takes place through punishments and rewards for human behavior. During operant conditioning, an association is made between a human behavior and immediately a consequence for that behavior. This is also identified as instrumental conditioning.

Embryology

Basic Embryology

A human begins life as a fertilized ovum. This single cell gives rise to the millions of cells that form the human body. In the first few days following fertilization, the developing embryo consists of a ball of cells. This implants on the wall of the uterus and begins to grow further, supported by nutrients and blood from the mother.

As the developing embryo grows in the first few weeks, there is increasing complexity from differentiation of the cells into specialized tissues to form specific organs. This differentiation is directed by genetic factors inherited via the chromosomes from both mother and father. Most organs are formed between 5 and 8 weeks of life. After that, there is continued growth and development to the time of delivery of the baby, which typically occurs following 38 to 42 weeks of gestation in utero.

Embryology Simplified

The three major embryologic categories of cells, called the germ cell layers, are:

Ectoderm: forms the epithelium that covers the body, and gives rise to cells in the nervous system

Endoderm: forms the gastrointestinal tract and associated structures involved in digestion

Mesoderm: forms the connective tissues and "soft" tissues such as bone, muscle, and fat

After birth, some cells within the body continue to proliferate, while others do not and remain or are lost in the aging process. Aging results from the inability of cells to maintain themselves or replace themselves.

The following discussion will introduce you to the types of cells and tissues that constitute the human body. Examples of the major cell types, along with the organs they compose, will be demonstrated with histologic sections.

The genes that direct cellular proliferation and development in embryologic life are "turned off" or suppressed once appropriate growth has been achieved. However, when some of these genes are "turned on" inappropriately because of mutations or alterations (oncogenes), or when the genes that suppress growth (tumor suppressor genes) become faulty later in life, then the result can be neoplasia.

I Aims

Behavioral embryology, which incorporates neurogenesis and developmental neurobiology, involves the study of the very early development of the nervous system and behavior with a viewtoward understanding how the formative periods of neural and behavioral development affect later stages of neurobehavioral ontogeny. The guiding philosophy is that neural and behavioral development at any given point in time can only be comprehended fully in light of the immediate and remote developmental history of the organism. For atruly comprehensive picture, the forwardreference of development must also be considered. A most important and pervasive aspect of embryonic behavior is its anticipatory or preparatory naturecrucial adaptive functions always develop well in advance of their necessity for the survival of the newborn, and several writers have emphasized that aspect of development in particular (e.g., Anokhin, 1964; Carmichael, 1970; Coghill, 1929).

A subsidiary aim of behavioral embryology involves the establishment of detailed and intimate relationships between neuroanatomy, neurophysiology, neurochemistry, and behavior. It is felt that these relationships can be established most readily and most meaningfully during the formative stagesof embryonic development, at which time the investigator is in a position to actually observe the increasingly complex changes in organization manifest themselves. A naturalistic theme pervades behavioral embryology in that most studies involve living specimens in their ordinary surroundings and, as far as is possible, there is an attempt to relate the results of in vitro studies to the in vivo and in situ conditions.

To paraphrase the words of Pearl (1904), the study of the ontogenetic history of an organismis regarded of prime importance in elucidating the adult condition. This method of study can gain thecomplete explanation of many structures and functions which are inexplicable when only the adult condition is considered. Thus, in many quarters, embryological study has come to be regarded as a necessary part of almost any anatomical, physiological, or behavioral investigation which aims at completeness, including human psychology. [See, for example, the recent review of behavioral embryology by Trevarthen (1973) for The Handbook of Perception. Carmichael's classical review of the older literature has been a standard feature of handbooks of child psychology for many years (Carmichael, 1933, 1970).]

In sum, the developmental method is basic to all disciplines which deal with organisms, whether from the genetic, biochemical, anatomical, physiological, behavioral, or psychological points of view, and behavioral embryology pushes this method of study to its logical extreme. The developmentalmethod is an analytic tool par excellence.

Anatomy

General Anatomy | School of Podiatric Medicine

Definition

General Anatomy, Anatomy 102, includes the developmental and general anatomy of the entire body excluding the lower extremity. The Fetal Period of development (ninth week to birth) will be the focal point for the embryological aspects of the course. This period of study will include an introduction to Teratology - the study of abnormal development. Three approaches to the material are used concurrently throughout the course: lectures present concepts of structure and function, films and radiographs demonstrate structures in specific regions, and dissections of cadavers reveal the interrelationships of all structures of the body.

Following the satisfactory completion of General Anatomy, the student will have an understanding of the relationship between the developmental processes and the other primary anatomical sciences: gross anatomy, neuroanatomy and histology. The student will be able to describe and discuss, using proper anatomical terminology, the embryological development and gross structural organization of the following body regions:

The student will demonstrate, through successful completion of both didactic examinations and laboratory practicals, a working knowledge of the general anatomy of the various somatic and visceral systems, including organogenesis, of these body regions and their visceral contents. While all body systems will be studied, the musculoskeletal, nervous and circulatory systems will receive the most emphasis because of their direct functional significance to the lower extremity. The student will achieve an understanding of general anatomy as a series of regions which are integrated by the different systems into the entire human body. This knowledge will provide background for courses in Lower Extremity Anatomy.

General Anatomy is included in the podiatric curriculum because it is necessary that the podiatrist understand the fundamental anatomy of the entire body in order to deal successfully with a specialized part of it. This course provides not only a basic foundation in human anatomy which will be of use in later courses but also an appreciation of the fact that the foot is not an isolated entity.

A working knowledge of gross and developmental anatomy will give the student of podiatric medicine an understanding of three-dimensional anatomical relationships. This ability is necessary in order to evaluate a patient when conducting a complete physical examination. It will also increase the podiatrist's ability to communicate with other physicians.
