A & P Intro
the branch of science that deals with the structure
What is anatomy
near the surface
superficial
cavity that houses the brain
cranial cavity
means a body part is above another part
Superior
means a body part is lower than another body part
Inferior
the branch of science that studies the functions of body parts
What is physiology
describes parts that are more internal than superficial
deep
Cavity that contains the spinal cord within sections of the back bone
What is the vertebral cavity
means toward the front
Anterior
means toward the back
Posterior
Requirements of organisms (5)
water, food, oxygen, heat, pressure
the internal environment remains stable
Homeostasis
cavities that hold most of the internal organs
thoracic, abdominopelvic
an imaginary midline dividing the body into equal left and right
Medial
Means toward the side
lateral
Levels of organization
atoms, molecules, macromolecules, cell, organelles, tissue, organs, organ systems, organism
when receptors measure deviations to initiate a needed change in homeostasis
negative feedback
cavity enclosed by the hip bones
pelvic cavity
refers to structures that have one on each side
bilateral
farther from the point of attachment to the torso
Distal
What are the 10 characteristics of life?
movement, responsiveness, growth, reproduction, respiration, digestion, absorption, circulation, assimilation, excretion
three lines that bisect the body
Transverse- top and bottom
Sagittal- divides the body left and right
Frontal- divides anterior and posterior
cavity containing the eyes
Orbital cavity
closer to the point of attachment to the torso
Proximal
refers to structures of the same side- right lung and right kidney
ipsilateral
