is the master controlling and communicating system of the body
causes a response
is a process which nervous system decide what should be done at each movement.
The key to neural communication
central nervous system, consists of the brain and spinal cords
Central nervous system
occupy the dorsal body cavity
the integrating and command center of the nervous system
CNS, central nervous system.
peripheral nervous system, the part of the nervous system outside the CNS, consiss mainly of the nerves, bundles and axons, that extend from the brain and spinal cord
peripheral nervous system
spinal nerves and cranial nerves serve as the communication lines that link all parts of the body to the CNS
Carry impulses to and from the spinal cord
Carry impulses to and from the brain.
consists of nerve fibers that convey impulses to the central nervous system from sensory receptors located throughout the body.
somatic afferent fibers
sensory fibers coveying impulses from the skin, skeletal muscles, and joints.
visceral afferent fibers
those transmitting impulses from the visceral organs.
transmits impulses from the CNS to effector organs, which are muscle and glands.
2 parts of motor division
Autonomic Nervous System and Somatic Nervous System
Autonomic Nervous System
Somatic Nervous System
consists of visceral motor nerve fibers that regulate the activity of smooth muscles, cardiac muscles, and glands.
consists of somatic motor nerve fibers, axons, that conduct impulses from the CNS to skeletal muscles.
Voluntary nervous system
somatic nervous system, which allow us to consciously control our skeletal muscles.
Involuntary nervous system
autonomic nervous system, which we generally cannot control such activities as the pumping of our heart or the movement of the food through our digestive tract.
2 functional subdivisions of ANS
the sympathetic and the parasympathetic.
