⩥ three types of neurons.
Answer: 1. interneurons= singles from one neuron to another
2. motor neurons= spinal cord or brain to other parts of the body
3. sensory neurons= body to spinal cord or brain
⩥ central nervous system.
Answer: brain and spinal cord
⩥ peripheral nervous sytem.
Answer: all the nerves in the body
⩥ CNS: four major sections of the brain.
Answer: 1. cerebrum= largest part of the brain (80%), left and right
hemispheres
2. diencephalons= center part of the brain
3. cerebellum= rear part of the brain
4. brain stem= connects the cerebrum and cerebellum to the spinal cord
,⩥ PNS.
Answer: 1. voluntary nervous system (somatic)= signals skeletal
muscles to contract voluntary movements
2.involuntary nervous system (autonomic)= relates the contraction of
internal organs, heart rate, digestion, and breathing
⩥ skeletal system.
Answer: -major function= to provide form and shape to the body
-axial skeleton= skull, rib cage, vertebral column
-appendicular skeleton= upper and lower extremities
-206 bones, 177 voluntary movement
-synovial joints= 80% of joints in body
⩥ muscular system.
Answer: - a single muscle is built from many bundles of muscle fibers
called fascicule
⩥ three types of muscle tissue.
Answer: 1. cardiac= walls of the heart
2. smooth= composes the epithelial of other hollow organs
3. skeletal= attached to skeleton, voluntary
⩥ three muscle actions.
, Answer: 1. concentric= muscle fibers are shortened, contractions
2. ecentric= muscles lengthen
3. isometric= tension on the muscle
⩥ three types of muscle pain after workout.
Answer: 1. muscle soreness
2. muscle and joint soreness= few hours after workout
3. delayed-onset muscle soreness (DOMS)= lasts for a few days
⩥ cardiorespiratory system.
Answer: -offer oxygen, protective agents, and nutrients to the tissues of
the kinetic chain (muscular, articular, neural systems)
⩥ cardiovascular system three compounds.
Answer: 1. heart
2. blood vessels carrying blood between heart and tissue
3. blood
⩥ respiratory sytem (pulmonary system).
Answer: -made up of soft tissue and skeletal structures
-major function= all cells function properly
