A brief contraction of all muscle fibers in a motor unit in response to a single action potential traveling down the somatic motor neuron is known as a muscle twitch. This twitch consists of three phases: the latent period, contraction phase, and relaxation phase. It represents the basic unit of muscle contraction and is essential for understanding muscle function and physiology.
What else can I help you with?
Is an effector of a skeletal muscle a somatic reflex?
Yes, the effector of a skeletal muscle is part of a somatic reflex. Somatic reflexes involve the contraction of skeletal muscles in response to a stimulus, and the effector in this case is the skeletal muscle itself that carries out the response.
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 is somatic reaction?
A somatic reaction is a physical response that occurs in the body as a result of psychological or emotional stimuli. It can manifest as symptoms such as increased heart rate, sweating, or muscle tension in response to stress or anxiety. Somatic reactions are linked to the body's fight or flight response to perceived threats.
Which pns systems controls skeletal muscles?
The somatic nervous system controls skeletal muscles. It is responsible for voluntary movement and receives motor information from the brain to stimulate muscle contraction.
What type of response occurs in a persons somatic nervous system when he or she touches a pot of boiling water?
they would react to it

What is somatic theory?
somatic theory is a response that is shown physically.
What is patellar knee-jerk reflex a somatic or autonomic reflex?
yes, the knee relfex felt when tapped just below the knee cap on the patellar tendon is a somatic reflex which is a contraction of skeletal muscles. the opposite would be autonomic relfexes which consist of contractions of smooth or cardiac muscle or secretion by glands.
What is somatic reaction?
A somatic reaction is a physical response that occurs in the body as a result of psychological or emotional stimuli. It can manifest as symptoms such as increased heart rate, sweating, or muscle tension in response to stress or anxiety. Somatic reactions are linked to the body's fight or flight response to perceived threats.
What is the neurotransmitter in a somatic motor pathway?
The neurotransmitter in a somatic motor pathway is acetylcholine. It is released by motor neurons at the neuromuscular junction to stimulate muscle contraction.
Which pns systems controls skeletal muscles?
The somatic nervous system controls skeletal muscles. It is responsible for voluntary movement and receives motor information from the brain to stimulate muscle contraction.
Voluntary movements are under the control of the?
The somatic nervous system controls the skeletal system and voluntary movement by stimulating muscle contraction. Parts of the somatic nervous system are spinal nerves, cranial nerves, association nerves.
What is the difference the somatic nervous system and the autonomic nervous system?
Autonomic is the automatic nervous system eg pain response (something you cannot not control) while the somatic nervous system is the thing we can control.
When someone touches a hot stove the rapid automatic preprogrammed response that preserves homeostasis is provided by what?
Somatic reflex
Jhindra's twitching facial muscles were a response to the stress of moving to a new country the doctor said?
Jhindra's twitching facial muscles were a response to the stress of moving to a new country the doctor said it was a somatic response.
In response to a muscle being overstretched a muscle spindle generates a somatic spinal reflex that ultimately causes what response?
Both contaction of the agonist muscle and relaxation of the antagonist muscle
