What are the two subdivisions of the motor subdivision of the peripheral nervous system?
The two subdivisions of the motor subdivision are the somatic nervous system and the autonomic nervous system. The somatic nervous system transmits action potentials from the CNS to skeletal muscle, and the autonomic nervous system transmits action potentials from the CNS to smooth muscle, cardiac muscle, and glands.
What is controlled by the somatic division of the PNS?
The somatic division of the peripheral nervous system controls voluntary movements, such as skeletal muscle contractions. It also transmits sensory information from the skin, muscles, and joints to the central nervous system for processing.
The efferent division of the peripheral nervous system innervates?
A muscle or a gland. Efferent fibers carry information away from the CNS to innervate tissues that perform functions; such as a gland, a smooth muscle, a skeletal muscle, or cardiac muscle. The antonym to efferent would be afferent.
What nerves innervates the smooth muscle of the digestive viscera?
The somatic nervous system consists of peripheral nerve fibers that send sensory information back to the CNS.
What are the two divisions of the peripheral system?
The two divisions of the peripheral nervous system are the somatic nervous system, which controls voluntary muscle movements, and the autonomic nervous system, which regulates involuntary bodily functions.
The branch of the nervous system that receives sensory information and controls muscle movements is the?
somatic nervous system which is a part of peripheral nervous system.
Neurotransmitter used to cause muscle contraction?
A neurotransmitter that causes muscle movement is called Acetylcholine. Acetycholine acts as on both the central nervous system and the peripheral nervous system.
Definition of somatic division?
The somatic division of the peripheral nervous system controls voluntary movements and sensory information processing. It includes motor neurons responsible for skeletal muscle contractions and sensory neurons for detecting external stimuli.
What nervous system controls the skeletal muscle contractions?
The central nervous system supplies the body and muscle contraction. Striated muscle (skeletal muscle) contract voluntary with exception of the heart which is striated involuntary smooth muscle.
The motor neurons of the efferent division of the pns carry?
Motor neurons of the efferent division of the peripheral nervous system carry signals from the central nervous system to muscles and glands, controlling voluntary and involuntary movements. They are responsible for muscle contractions, gland secretion, and other motor functions.
Parts of peripheral nervous system?
The peripheral nervous system consists of two main parts: the somatic nervous system, which controls voluntary muscle movements and receives sensory information, and the autonomic nervous system, which regulates involuntary processes like heart rate, digestion, and breathing.
What are the comonents of the nervous system?
The brain and spinal cord are part of the C.N.S.(Central Nervous System) The nerves from senses -> brain -> motor neuron -> muscle are part of the P.N.S. (Peripheral Nervous System)
