Define Medial (Ch 1)
Give this one a try later!
Medial describes the middle or direction toward the middle of the body.
The hallux is the medial toe.
Identify body cavities. (Ch 1)
,Give this one a try later!
Posterior cavity:
cranial cavity: houses the brain
spinal cavity: (or vertebral cavity) encloses the spinal cord.
Anterior cavity:
The thoracic cavity: enclosed by the rib cage. contains the
lungs and the heart, which are located in the mediastinum.
abdominopelvic cavity: the largest cavity in the body.
Pleural cavity: surrounds the lungs, reduces friction
between the lungs and the body wall.
Peritoneal cavity: surrounds several organs in the
abdominopelvic cavity, cavity reduces friction between the
abdominal and pelvic organs and the body wall.
Pericardial cavity: surrounds the heart, reduces friction
between the heart and the wall of the pericardium.
Define Proximal (Ch 1)

Proximal describes a position in a limb that is nearer to the point of
attachment or the trunk of the body. The brachium is proximal to the
antebrachium.
Describe endocytosis and exocytosis in terms of function and direction. (Ch 3)

, Endo: is the process of a cell ingesting material by enveloping it in a
portion of its cell membrane, and then pinching off that portion of the
membrane. "taking into cell"
Exo: the process of a cell exporting material using vesicular transport
(deliver material elsewhere in/out of the cell using vesicles) "taking out of
cell"
Define facilitated diffusion in terms of substances transported, direction, and mode of
action. (Ch 3)

the passive movement of molecules along the concentration gradient. It is
a selective process, i.e., the membrane allows only selective molecules and
ions to pass through it. It, however, prevents other molecules from passing
through the membrane.
Channel protein: not specific
Carrier protein: typically for specific substance
Aquaporin: channel proteins for water
Describe the various organizational levels of the human body. (Ch 1)
Give this one a try later!
Chemical: atoms and molecules
Cellular: organelles develop within cells
Tissue: cells work together to perform a specific function.
Organ: 2 or more tissues work together to perform a specific function.
Organ System: 2 or more organs work together to perform a specific
function.
Organismal: Organ systems work together to keep organism alive.
