Communication network within the body
Nervous system
Brain and spinal cord; controls anf interpret information
Central Nervous System (CNS)
Nerves connecting the CNS to the rest of the body and thr environment
Peripheral nervous system
Peripheral nervous system subdivisions
Somatic and autonomic
Outer areas body and skeletal muscle; voluntary
Somatic
involuntary system (ex. heart, digestion)
Autonomic
Autonomic subdivisions
Parasympathetic and Sympathetic
function unit of the nervous sytem
Neuron
transmits nerve impulses from CNS to effector sites
Motor (efferent) neurons
respond to stimuli; transmit nerve impulses from effector sites to CNS
Sensory (afferent) neurons
sense distortion in body tissues
Mechanoreceptors
respond to pressure, acceleration, and deceleration of joints
Joint Receptor
sense changes in muscular tension
Golgi tendon organs (GTO)
sense changes in muscles
Muscle spindles
connect muscle to bone; provide anchor for muscles to produce force
tendons
outer layer of connective tissue surrounding a muscle
fascia
bundle of individual muscle fibers
fascicles
