anatomy
the study of the shape and structure of body parts
physiology
the branch of biological science that studies and describes how body parts work or function
homeostasis
the tendency of the body's systems to maintain a relatively constant or balanced internal environment
metabolism
the term that indicates all chemical reactions occurring in the body.
integumentary system
control of body tempature
thermoregulation
controlled by negative feedback
cephalic
refers to head region
thoracic cavity
pericardial (heart) and pleural (lungs) cavities
positive feedback
body is moved away from homeostasis, normal range is lost, used to speed up process, exaggerates variations. Ex. Child labor & contractions
negative feedback
opposes variation. Restores homeostasis. The response of the effecter negates the stimulus, body is brought back into homeostasis.
superior
toward the head end or upper part of a structure of the body
inferior
away from the head end or toward the lower part of the body
anterior
toward or at the front of the body
posterior
toward the backside of the body
medial
toward the midline of the body
proximal
close to the orgin of the body part or at the point of attachment of a limb to the body trunk
distal
farther from the orgin of a body part or the point of attachment of a limb to the body trunk
superficial
toward or at the body surface
deep
away from the body surface; more internal
anatomical terms
describe body regions, anatomical positions and directions and body sections
nervous system
responds rapidly resulting in short term changes to maintain homeostasis
endocrine system
produces effects that last for days or longer to maintain homeostasis
ventral body cavity
contains organs of the respiratory, cardiovascular, digestive, urinary, and reproductive systems. Contains abdominopelvic and thoracic cavity.
diaphragm
a flat muscular sheet divides the ventral body cavity into a superior thoracic cavity bounded by the chest wall, and inferior abdominopelvic cavity.
viscera
a delicate layer called serous membrane likes the walls of these internal cavities and covers the surfaces of the enclosed viscera. Covers the organ
body cavities
protect internal organs from accidental shock and allow them to change shape and size.
serous membranes
line body cavities and cover organs
skeletal system
provides support; protects tissues; stores minerals; forms blood
muscular system
produces movement and locomotion; provides support; generates hear
cardiovascular system
transport cells and dissolved materials, including nutrients, wastes and gases.
lymphoid system
defends against infection and disease; returns tissue fluid to the bloodstream
