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 else can I help you with?
Would damage to somatic motor neurons impair micturition?
Damage to somatic motor neurons would not impair micturition, as micturition is primarily controlled by autonomic motor neurons. Somatic motor neurons control voluntary muscle movements, while autonomic motor neurons control involuntary functions like bladder contractions during micturition.
What part of the brain coordinates complex somatic motor patterns?
The cerebellum is the part of the brain that coordinates complex somatic motor patterns by integrating sensory information and coordinating movement.
The somatic nervous system issues somatic motor commands that?
The somatic nervous system issues somatic motor commands that control voluntary muscle movements in the body. These commands are sent from the central nervous system to skeletal muscles, allowing for purposeful physical actions such as walking, reaching, and speaking.
Impulses are sent from the brain to the effector organs along what neurones?
Impulses are sent from the brain to the effector organs along motor neurons. These motor neurons are part of the peripheral nervous system and carry signals from the central nervous system to muscles and glands, allowing for coordinated movement and responses.
When you flex your biceps you are calling on the somatic sensory portion of nervous system?
Flexing your biceps primarily involves the somatic motor portion of the nervous system, which controls voluntary muscle movements. The somatic sensory system is responsible for detecting sensations like touch or pain in the skin, muscles, and joints. So, while you may be aware of the sensation in your biceps when you flex them, the actual movement is driven by the somatic motor system.
What effector cells are innervated by somatic motor neurons?
cardiac muscles and smooth muscle
What is the name of a neuron that transmits a neural impulse from the central nervous system through the spinal cord to a muscle?
The neuron that transmits a signal from the nervous system to an effector is a motor neuron.
What is principle of final common path as it pertains to somatic motor pathways?
The principle of final common path states that all somatic motor pathways converge on the alpha motor neurons in the spinal cord. These alpha motor neurons innervate skeletal muscles to produce movement. This convergence allows for integration of input from multiple sources before initiating a motor response.
What are the 5 steps to a reflex arc?
Arrival of stimulus, Activation of a sensory neuron, Information processing by an interneuron, Activation of a motor neuron, The response by an effector. Straight out of my anatomy text book.
What is the name of the neuron that contacts the effector organ?
Motor neurons are able to create a response in effector organs, muscles and glands by sending signals to them.
Where is the somatic motor cortex?
The somatic motor cortex is located in the human brain. It can be found in the posterior portion of the frontal lobe.
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.
A reflex arc begins with the stimulation of a what?
A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
Where are somatic motor neurons located?
in the CNS
What are the desired responses elicited by electrical stimulation treatment?
Subsensory stimulation, sensory stimulation, motor stimulation, noxious response.
Would damage to somatic motor neurons impair micturition?
Damage to somatic motor neurons would not impair micturition, as micturition is primarily controlled by autonomic motor neurons. Somatic motor neurons control voluntary muscle movements, while autonomic motor neurons control involuntary functions like bladder contractions during micturition.
How do impulses move in response to a stimulus?
to the brain, then to the effector through the motor neuron
