What else can I help you with?
Are neurons sometimes called skeletal muscles?
no
What is Skeletal muscles controlled by?
Skeletal muscles are controlled by motor neurons in the somatic branch of the peripheral nervous system, which is controlled by the central nervous system.
Impulses from motor neurons control the contraction of skeletal muscles?
false
What is an excitatory neurotransmitter secreted by motor neurons innervating skeletal muscles?
acetylcholine
Which fibers carry action potential to cause skeletal muscles to contract?
Alpha motor neurons
Neurons that carry signals from the CNS to skeletal are part?
Neurons that carry signals from the central nervous system (CNS) to skeletal muscles are known as somatic motor neurons. These neurons are responsible for controlling voluntary movements of the body by transmitting signals that stimulate muscle contractions.
Why does motor neuron disease result in paralysis of skeletal system?
Skeletal muscle contraction is activated by motor neurons in the spinal cord, which are themselves under control from motor neurons in the brain. Without nervous input, the muscles wont respond to volitional control.
Where are cell bodies of motor neurons to skeletal muscles located?
Motor neurons to skeletal muscles have cell bodies located in the ventral horn of the spinal cord. These cell bodies send signals through their axons to control muscle movement and are part of the somatic nervous system.
What PNS system controls skeletal muscles?
The somatic nervous system controls skeletal muscles. It is responsible for voluntary movements and receives input from sensory neurons to help coordinate muscle contractions.
What do PNS motor neurons do?
Peripheral nervous system (PNS) motor neurons are responsible for controlling voluntary movements of skeletal muscles. They receive signals from the central nervous system (CNS) and transmit them to the muscles to initiate movement. PNS motor neurons are essential for activities like walking, talking, and grabbing objects.
Can skeletal muscules be controlled?
Yes, skeletal muscles are under voluntary control, meaning that we can consciously decide when to contract or relax them to perform movements. This control is facilitated by the motor neurons in the brain and spinal cord that send signals to the muscles to initiate movement.
Where do nerve impulses first stimulate a skeletal muscle fiber?
The motor nerve cells control the skeletal muscle
