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.
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.
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.
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.
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)
Characteristic which defines the peripheral nerves system?
The easiest way to define the peripheral nervous system is to first define the central nevous system. the central nervous system consists of the brain and spinal cord. the peripheral nervous system is everything else. The peripheral nervous system (or PNS) is divided into the autonomic (involuntary like smooth muscle peristalsis in the gut) and somatic (voluntary, like flexing your arm to show off your muscles) nervous systems. The autonomic nervous system is again further subdivided into the parasympathetic nervous system (rest and digest) and the sympathetic nervous system (fight or flight).
Is the nervous system divided into three major parts?
The nervous system is divided into two parts: I. Central Nervous System a. Brain b. Spinal Cord II. Peripheral Nervous System a. Somatic Nervous System (voluntary muscle movements) b. Autonomic Nervous System (involuntary muscle movements) 1. Sympathetic Nervous System (flight or fight) 2. Parasympathetic Nervous System (rest and digest)
What is motor deficit?
A motor deficit is caused by either a malfunction of the central nervous system or a malfunction of the peripheral nervous system. Involuntary muscle contractions can also develop as a motor deficit.
Two main neural tissues found in the human body?
Nervous tissue is one of the four basic building block tissues in the human body (epithelial, connective and muscle tissue being the other three). Nervous tissue exists either as part of the central nervous system (CNS; brain and spinal cord) or the peripheral nervous system (PNS; cranial and peripheral nerves and ganglia). I assume this is what your question refers to.
What are the components of the nervous system?
The nervous system is composed of both central (brain and spinal cord) and peripheral components, with the latter having both somatic and autonomic (parasympathetic and sympathetic) subdivisions.
