What structure is the effector for the somatic motor stimulation?
The effector for somatic motor stimulation is the skeletal muscle. Somatic motor neurons innervate these muscles, leading to voluntary movements. The motor unit, consisting of a motor neuron and the muscle fibers it innervates, is responsible for muscle contraction in response to somatic motor stimulation.
What are general somatic efferent?
General somatic efferent (GSE) fibers are motor nerve fibers that originate in the spinal cord and are responsible for innervating skeletal muscles. They transmit signals from the central nervous system to the muscles, facilitating voluntary movements. GSE fibers are part of the peripheral nervous system and play a crucial role in controlling motor functions, such as walking and fine motor skills. These fibers are primarily associated with the lower motor neurons found in the spinal cord and brainstem.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
What is the role of the spindle fibers?
Spindle-shaped muscle fibers are skeletal muscles that produce external mobility to the body.
What travels from your brain to your skeletal muscle cells when you move?
When you decide to move, an electrical signal called an action potential is generated in your brain. This signal travels along your neurons and reaches the skeletal muscle cells via motor neurons. At the neuromuscular junction, a chemical called acetylcholine is released, which stimulates the muscle fibers to contract and initiate movement.
What are the fibers that carry information from the skin joints and skeletal muscles to the nervous system?
Somatic nerves from the somatic nervous system
What do somatic nerve fibers innervate?
Somatic nerve fibers innervate the structures responsible for conscious touch, pain, and temperature sensation in the skin, muscles, and joints. They are part of the peripheral nervous system and transmit sensory information from the body to the central nervous system.

The motor unit, consisting of a motor neuron and the muscle fibers it innervates, is responsible for muscle contraction in response to somatic motor stimulation.
Bone that consists of hardened fibers interspersed with many spaces?
Spongy bone provides lightweight support. Consists of hardened fibers interspersed with many spaces. Skeletal system made of calcium hardened collagen fibers that make it strong but flexible.
What is a group of skeletal muscle fibers?
A skeletal muscle
What neurotransmitter control the somatic nervous system and how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.

Is skeletal muscle made of muscle fibers?
Basically, yes. All muscle (skeletal, cardiac and smooth) are made of muscle fibers.
What motor neuron and all the muscle fibers it innervates called?
the motor unit
Network that stimulates the myocardium into contraction?
His bundle? or the Purkinje fibers?
Skeletal muscle fibers are encased in?
Endomysium
