1A Flashcards
Biology
The study of living organisms.
Physiology

Subdivision of anatomy meaning the study of the surface structures.
Developmental Anatomy (Embryology)
Subdivision of anatomy meaning the development of the body prior to birth.

Subdivision of anatomy comparing human structures to that of other animals.
Radiology
Subdivision of anatomy using radiation to visualize internal body structure.
Anatomical Pathology
Subdivision of anatomy meaning the study of tissue that departs from the normal and thus is diseased.
List the Organization of the body from smallest to largest.
Cell, tissue, organ, organ system, body.
Cell
Smallest unit of living matter and the characteristic building block of all plant and animal tissues.
Tissue
Collection of cells of similar structure and function.
Organ
Consists of two to more tissues blended in such a way as to form a structure, which can perform one function or related functions.
Organ System
Consists of one or more organs that act together in performing a major function of the body.
Body
Composed of the 12 organ systems.
Regional Method of Study
According to the natural subdivisions of the body.
- Head: facial region, cranium
- Neck
- Thorax
- Abdomen
- Pelvis
- Back (posterior aspect of thorax, abdomen, and pelvis)
- Trunk (combination of thorax, abdomen, pelvis, and back)
- Upper Limb (extremity): pectoral region, arm, forearm, and hand
- Lower Limb (extremity): gluteal region, thigh, leg, and foot
Systematic Method of Study
According to the major body systems; collections of organs that perform related functions.
Name the 12 Organ Systems.
Cardiovascular or Circulatory, Lymphatic, Respiratory, Digestive, Urinary, Integumentary, Skeletal, Muscular, Articular, Nervous, Endocrine, Reproductive
Cardiovascular or Circulatory System
Structures: Heart, blood vessels
Functions: Transports nutrients and oxygen cells, removes waste molecules that are excreted from the body.
Lymphatic System
Structures: Lymphatic vessels, nodes, supporting lymphocytes, and the lymphoid organs
Functions: Protects body from disease by purifying fluid. Involves white blood cells that produce antibodies.
Respiratory System
Structures: Lungs, pharynx, larynx, trachea
Functions: Conducts air, brings oxygen into lungs, and takes carbon dioxide out.
Digestive System
Structures: Mouth, esophagus, stomach, small and large intestine, teeth, tongue, salivary glands, liver, gall bladder, pancreas
Functions: Receives food and digests it into nutrient molecules, which enter the cells.
Urinary System
Structures: Kidneys, ureters, bladder, urethra
Functions: Rids the body of nitrogenous wastes and regulate the fluid level and chemical content of the blood.
Integumentary System
Structures: Skin, nails, hair, sebaceous glands, sweat glands, subcutaneous tissue
Functions: Provides support and protects underlying tissues, help regulate body temperature, contains receptors.
Skeletal System
Structures: Bones of the skeleton
Functions: Framework, Movement of the body
Muscular System
Structures: Muscles
Functions: Movement of the body
Articular System
Structures: Joints
Functions: Movement of the body
Nervous System
Structures: Brain, spinal cord, nerves
Functions: Conducts nerve impulses to muscles and glands and receive impulses.
Endocrine System
Structures: Hormones, endocrine glands
Functions: Secretes chemicals that serve as messengers between body parts, maintains proper functioning of reproductive organs.
Reproductive System
Structures: Reproductive organs
Functions: Reproduction in process of copulation
Anatomical Position
Refers to the position the body must be in when using anatomical planes and terms of reference.
Name the 5 criteria of anatomical position.
- Body Longitudinal
- Upper Limbs By Side
- Eyes Directed Forward
- Palms Directed Forward
- Toes Directed Forward
Planes of Reference
Planes that subdivide the total body or organs. There are 4 standard planes.
Median (Midsagittal) Plane
1 vertical plane passing through the body dividing it into equal right and left halves.
Sagittal Plane
Any vertical plane that parallels the median plane (so it is lateral to the median plane) and divides the body into unequal right and left parts.
Frontal (Coronal) Plane
Any vertical plane at a right angle to the median plane that divides the body into front and back parts.
Horizontal (Transverse) Plane
Any plane at a right angle to both the median and frontal planes that divides the body into upper and lower parts.
Terms of Reference
Must always be used with the body in the anatomical position. There are 6 pairs of terms
Medial/Lateral
M: Nearer the median plane.
L: Farther away from the median plane.
Anterior(Ventral)/Posterior(Dorsal)
A: Nearer the front
P: Nearer the back
Superior(Cephalic)/Inferior(Caudal)
S: Nearer the upper (head) end.
I: Nearer the lower (tail) end.
The terms Cephalic and Caudal are not used very often, but they are used more frequently when describing the brain.
Proximal/Distal
P: Nearer the attached end of a limb.
D: Farther away from the attached end of a limb.
Internal/External
I: Nearer the center of an organ or cavity.
E: Farther away from the center of an organ or cavity.
Superficial/Deep
S: Nearer the surface of the body.
D: Farther away from the surface of the body.
Supine Position
Lying on back, belly is upward
Prone Position
Lying on front, back is upward
