What is refered to as the somatic nervous system?
A full explanation at :- http://en.wikipedia.org/wiki/Somatic_nervous_system Basically, it is the nerve system that control voluntary body movements
What is a somatic nervous system?
A nerve that is under your conscious control and stimulates skeletal muscles also controls voluntary movements, such as writing, talking, smiling or jumping
Which nerve supplies the pelvic floor?
The pudendal nerve (part of the somatic nervous system, voluntary control) innervates the pelvic floor. It also innervates the external urethral sphincter; the internal urethral sphincter is innervated by the pelvic nerve (part of the parasympathetic nervous system, involuntary control).
What causes primary lateral sclerosis?
Motor neuron diseases like primary lateral sclerosis develop because the nerve cells that normally control the movement of voluntary muscles degenerate and die.
What is the function of the two groups of nerves making up the peripheral nervous system?
Somatic nervous system: Associated with the voluntary control of body movements via skeletal muscles Autonomic nervous system:operates independently of voluntary control, although certain events, such as emotional stress, fear, sexual excitement, and alterations in the sleep-wakefulness cycle, change the level of autonomic activity.
What part of the brain contains nerve centers which help control eye movement?
the neuron that controls our eye movement and it ism important
What part of the brain contains nerve centers which help control eye movement and the size of the pupils?
Oculomotor Nerve
A nerve impulse that originates in the precentral gyrus of the cerebrum?
A nerve impulse that originates in the precentral gyrus of the cerebrum is responsible for initiating voluntary muscle movements. It travels along the corticospinal tract, crosses over to the opposite side of the brainstem, and descends through the spinal cord to reach the muscles that are involved in the intended movement. This process allows for precise and coordinated control of voluntary movements throughout the body.
Which of these parts receive nerve impulses from the central nerous system causing muscle fibers to contract?
The motor neurons carry impulses from the central nervous system to the muscles. These impulses may be generated autonomically (instinctively) or through voluntary control by the brain.
Difference between voluntary and nonvoluntary muscles?
The only unvoluntary muscle is cardiac muscle. Heart is cardiac muscle. Unvoluntary muscle does not need nerve system in order to work. It works even if we are not in concious. Voluntary muscles need nerve system to move. The coordinating centre in our brain send nerve impulses to the muscles for various movement such as running and chewing. Instances of voluntary muscles are smooth muscle and skeletal muscle.
What substance aids the transmission of nerve impulses?
Acetylcholine is one of many neurotransmitters. It's the primary NT of voluntary muscular movement. Myelin insulates the axons, allowing nerve impulses to be transmitted faster.
What Contains the nerve centers which help control eye movement and size of pupils?
the brain
