Basic Exercise Science - Nervous System
Human Movement System (HMS)
The combination and interrelation of the nerevous, muscular and skeletal system
Billions of cells specificalluy designed to provide a communication network within the human body
The ability of the nervous system to sense changes in either the internal or external environment
The ability of the nervous system to analyze and interpret sensory information to allow for proper decision making, which produces the appropriate response
The neuromuscular response to the sensory information
The cumulative sensory input to the CNS from all mechanoreceptores that sense body position and limb movement
The functional unit of the nervous system
Sensory neuron (afferent)
Transmit nerve impulses FROM effector sites (muscles and organs) TO the brain and spinal cord...
Signal FROM muscles TO brain
Transmit nerve impulses from one neuron to another
Motor neurons (efferent)
Transmit nerve impulses FROM the brain and spinal cord TO effector sites...
Signal FROM brain TO effector site
Central Nervous System (CNS)
The portion the nervous system that consists of the brain and spinal cord
Peripheral Nervous System (PNS)
Cranial and spinal nerves that spread throughout the body
Muscle SpindlesSensory receptors responsible for sensing distortion in body tissues
Receptors sensitive to change in length of the muscle and the rate of that change
Receptors sensitive to change in tension of the muscle and the rate
of that change.
Cause the muscle to relax to prevent muscle from excessive stress.
Receptors surrounding a joint that sespond to pressure, acceleration and deceleration of the joint.
