Neuromuscular system incorporates which systems
nervous system and muscular system
nervous system gathers information from the _________ and ________ environment and communicates the necessary change to the muscular system.
internal and external
cells called neurons pass information using an _____
electrical nerve impulse
neuron is
cell of the nervous system that conducts the electrical nerve impulse
fibrous tissue that produces force and motion to move the body or produce movement in parts of the body
muscle
What is contraction?
the process leading to shortening and/or development of tension in a muscle
what is the CNS? And what does it consist of ?
Central Nervous system. Consisting of brain and spinal cord
Spinal Cord connects?
the peripheral nervous system to the brain
What is the PNS? what does it consist of?
Peripheral Nervous System. Consists of extensive network of spinal nerves carrying sensory or afferent information towards the spinal cord and brain and motor or efferent information away from the brain and spinal cord. auntommic and somatic divisions
Somatic Division is
voluntary and controls the skeletal muscles of the body
Autonomic or visceral division is?
involuntary and controls the visceral or cardiac muscles of organ system
what is a dendrites of a neuron?
pick up stimulus which is sent through the body of the cell along to the axon terminal branches
what is the axon of a neuron
long singular tail like extension which sends impulses from neuron body to the branching ax terminal
synapse
structure that allows neurons to pass signals to other neurons, muscles or glands
Contraction of muscle
occurs when thin actin filaments slide past the thicker myosin filaments causing the sarcomere unit to shorten or contract
ALS/amyotrophic lateral sclerosis/Lou Gehrig’s Disease
motor neurons degenerate and die leading to loss of voluntary muscle movement
Muscular dystrophy
affects both voluntary and involuntary muscles. abnormal genes interfere with production fo proteins needed to form healthy muscles
_____ neurons carry stimulus towards the central nervous system while _____ neurons carry impulses away from the central nervous system
Sensory and motor
