Section 1
(50 cards)
ligament
connects bone to bone
node of Ranvier
gap between myelin sheaths that expose the axon, help accelerate impulses
anatomy
study of the biological form of an organism
nervous tissue
tissue that senses stimuli, integrates and analyzes them, and controls the body's response
gland
a group of specialized epithelial cells that are capable of producing secretions
homeostasis
tendency to maintain a balanced or constant internal state
respiratory system
system that is responsible for gas exchange
axon
conduct and propagate impulses
tendon
connects muscle to bone
endocrine system
system that is responsible for sending out hormones that regulate homeostasis in the body
physiology
study of the biological functions an organism performs
connective tissue
tissue that provides support for the body and connects all its parts; has an extracellular matrix (secreted by fibroblasts) made of collagen, elastin and reticulin
chondrocyte
cartilage, connects and cushions joints
Schwann cell
support and insulates axons using a myelin sheath
smooth muscle
involuntary, in walls of blood vessels and viscera, one nucleus
dendrite
receive stimuli; highly branched extensions
epithelial tissue
tissue that covers outside of the body and lines organs and cavities; tightly bound to form a protective layer; highly regenerative
muscular tissue
tissue that moves the body and its parts; striated muscles contain actin and myosin filaments for contraction
osteocyte
bone, calcified cells that provide sturdy support
tissue
a group of related cells
nervous system
system that is responsible for body intercommunication, picking up and responding to stimuli, and stimulating movement
integumentary system
system that is responsible for protecting the outer body
sensory neuron
pick up stimuli from the environment and send to the brain
negative feedback
process that reduces stimuli to return organism to homeostasis
plasma
liquid part of blood
interneuron
neurons in the CNS that communicate internally and connect sensory to motor neurons; are responsible for reflexes
adipose
fat reserve cells
erythrocyte
red blood cell
cell body
contains nucleus of the neuron
organ
one functional unit of tissues
skeletal system
system that is responsible for creating a rigid framework
stimulus
change or signal in the environment that can make an organism react
immune system
system that is responsible for protecting the inner body from pathogens
circulatory system
system that responsible fordistributing nutrients, oxygen and other vital materials throughout the body
urinary system
system that is responsible for waste elimination
muscular system
system that is responsible for carrying out voluntary movement
levels of organization
1. cell 2. tissue 3. organ 4. organ system
digestive ssytem
system that is responsible for food breakdown and nutrient absorption
cardiac muscle
involuntary, single nucleated, striated, have gap junctions to link adjacent cells and help the heart perform as one unit (intercalated disks)
saltatory conduction
rapid jumping of an impulse from node to node
organ system
organs working together to perform a specific function
neuron
main cell of the nervous system
thrombocyte
platelet
loose connective tissue
less packed connective tissue which makes it loose and flexible, includes adipose
skeletal muscle
voluntary, attached to bones, multinucleated, striated
neuroglia
cells that support neurons (ex: Schwann cells)
reproductive system
system that is responsible for producing gametes and reproducing
leukocyte
white blood cell
motor neuron
sends impulses to muscles to create movement
dense connective tissue
have large amounts of either collagen fibers (making them strong) or elastic fibers, or both, includes tendons and ligaments
