Characteristics Of Life Flashcards
(24 cards)
Metabolism
The SUM Of All The Chemical Processes That Occur In The Body
Catabolism
Involves breaking down large, complex molecules into smaller, simpler ones
Anabolism
Uses the energy from catabolism to build the structural and functional components of the body
Analgesic
Drug That Relieves Pain
Responsiveness
The ability to detect and respond to changes in the external or internal environment
Differentiation
This is the change that a cell undergoes to develop from an unspecialized to a specialized state
Cranial Skeleton
Consists of the cranium, the mandibles, hyoids (supports the tongue)
Ventral
Belly Or Underside Of The Body
Cranial
Towards The Head
Caudal
Closer To The Tail Than Another Structure
Dorsal
Towards The Back
Proximal
Closer to the point of attachment (origin) to the body than another structure
Distal
Farther from the point of attachment to the body than another structure
Dorsal Plane
Plane that divides the body into dorsal (back) and ventral (belly) parts
Transverse Plane
Divides Body Into Cranial & Caudal Parts
Sagittal Plane
A vertical plane that divides the body into right and left sides
If such a plane passes through the midline of the body and divides it into equal right and left sides, it is called a midsagittal (median)plane
Not Equal Left & Right Sides - Parasagittal Plane
Cranial Cavity
Hollow space in the skull that contains the brain
Spinal Cavity
Hollow space within the spinal column that contains the spinal cord
Thoracic (Chest) Cavity
Hollow space within the ribs between the neck and diaphragm that contain the heart and lungs
Abdominal Cavity
Hollow space between the diaphragm and pelvic cavity that contains the major organs of digestion
Pelvic Cavity
Hollow Space Containing Sigmoid Colon, Rectum, Anus, Urinary Bladder, & Reproductive Organs
Serous Membrane
A thin, double-layered, slippery tissue called lining the walls, body cavities, and organs
Visceral Serous Membrane
The inner membrane contacting the organ
Parietal Serous Membrane
The outer membrane which lining the cavity
