nerve system and muscle contraction
definition of nerve
The main working unit of the nervous system that functions to conduct electrical impulses that are formed due to a stimulus.
structure of nerve
dendrit
axon
nucleus
body cell
nodus ranvier
schwann cell
aferen
carries impulses to the central nervous system
eferen
carries information from the CNS to the effector organ
nerve electricity
occurs in nerve cells to conduct impulses or stimuli
action potential
a single electric wave that will be transmitted through the cell membrane until it reaches the tip of the axon, causing the emission of neurotransmitters or ions to the postsynaptic neuron membrane
membrane potential
the electrical potential difference between the outer and inner walls of a cell membrane that ranges from about -50 to -200 millivolts.
process of nerve impulse formation
The formation of this nerve impulse is caused by a condition called depolarization
process of nerve impulse transmission
the transmission of impulses from one nerve cell to another nerve cell is conducted through the synapse
synapse
the point of intersection between the axon terminal of one neuron and another neuron
neuromuscular junction
the location where the axon terminal of the neuron meets the motor end plate
mucle skeletal
active locomotion
structure of muscle skeletal
muskulus caput
musculus venter
musculus kaudal
process of muscle contraction
Muscle contraction begins with a nerve impulse. At the time of the arrival of the implus, the synapses or connection areas between the nervous system in humans and muscle fibers are filled with acetylcholine.
relaxation
the place used to bind myosin to the smooth part of the filament will be inhibited by a regular protein called tropomyosin.
energy source for muscle contraction
ATP
body coordination mechanism
Coordination of body movements involves muscles, joints, and also nerves
