Anatomy

Anatomy

focuses on the physical structure and organization of living things

Physiology

focuses on the functions and processes carried out by living things

Levels of organization(largest to smallest)

Organism, organ system, organ, tissue, cells, chemical/molecule(atoms)

Anatomical Position (Surface position)

Supine

face up

Prone

face down

frontal plane

perpendicular to the ground and divides the body into dorsal (posterior or back) and ventral (anterior or front) portions.

Sagittal plane

vertical plane that passes through the body longitudinally(vertically). It divides the body into a left section and a right section.

transverse plane

also known as an axial plane or cross-section → divides the body into cranial (head) and caudal (tail) portions

ventral

toward the front (in humans only) or belly

dorsal

toward the back or spine

anterior

front side of the body

posterior

the back of a structure, or a structure found toward the back of the body.

cephalic

head or the head end of the body (Cephalic is synonymous with cranial)

rostral

something situated toward the oral or nasal region, or in the case of the brain, toward the tip of the frontal lobe.

caudal

towards the tail or away from the head-end of the body.

superior

above/to the top or towards the head-end of the body

inferior

below/towards the bottom or away from the head-end of the body.

medial

toward the median plane/towards middle

lateral

to the side of, or away from, the middle of the body

proximal

closer to the point of attachment or origin

distal

further from the point of attachment or origin

ipsilateral

(IP-sih-LA-teh-rul) On the same side of the body as another structure or a given point.

contralateral

occurring on, affecting, or acting in conjunction with a part on the opposite side of the body.

Body Cavities (functions - 2)

Protect delicate organs

Permit change in size and shape w/o damage to nearby organs

Ventral cavities
