What sends nerve impulses to the CNS to be processed?
surrounds most axons & made almost of all fat- protects & insulates nerve fibers from each other & speeds transmission of nerve impulses Sensory Neurons transmits impulses from sensory receptors toward the cns
What neurons are the most common in the CNS?
- The soma is the cell body where the nucleus lies, and which controls the cells and is also where proteins are produced to maintain the functioning of the neuron.
- The dendrites are the branch-like structures found at the ends of the neuron. ...
- The axon is the long extension structure stemming from the soma. ...
What nerve carries impulses toward the CNS?
What carries nerve impulses toward the CNS? Cranial nerves, spinal nerves, and ganglia make up the peripheral nervous system. The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS. What transmits messages to CNS?
What are collections of nerve cell bodies inside the CNS?
- Axillary nerve - innervates the deltoid muscle and shoulder, along with the posterior aspect of the upper arm.
- Musculocutaneous nerve - innervates anterior skin of upper arm and elbow flexors.
- Radial nerve - innervates dorsal aspect of the arm and extensors of the elbow, wrist, and fingers, abduction of thumb.
What are stimuli in the nervous system?
Stimuli. changes, occurring within or outside the body, that affect nervous system functioning. Afferent Neuron. neuron that conducts impulses toward the CNS from the body periphery. Neurotransmitters. chemicals released by neurons that stimulate other neurons, muscles, or glands. THIS SET IS OFTEN IN FOLDERS WITH...
What is the association neuron?
Association Neuron. neuron, serving as part of the conduction pathway between sensory and motor neurons. Nodes of Ranvier. gaps in a myelin sheath. Ganglion. collection of nerve cell bodies found outside the CNS. Efferent Neuron. neuron that conducts impulses away from the CNS to muscles and glands. Proprioceptors.
What are the sensory organs found in the skin?
Cutaneous Sense Organs. sensory receptors found in the skin, which are specialized to detect temperature, pressure changes, and pain. Schwann Cells. specialized cells that myelinate the fibers of neurons found in the PNS. Synapse.
Which part of the nervous system is responsible for communication lines?
a major subdivision of the nervous system that serves as communication lines, linking all parts of the body to the CNS. Afferent Neuron. Neuron that conducts impulses toward the CNS from the body periphery. Cutaneous sense organs.
What is the system that processes sensory input?
Nervous System. 1: it uses its millions of sensory receptors to motion changes occurring both insides and outside the body; the gathered information is called sensory input 2: it processes and interprets the sensory input and makes decisions about what should be done a.
Where are sensory receptors found?
sensory receptors found in the skin, which are specialized to detect temperature, pressure changes, and pain. sensory receptors found in muscle and tendons that detect their degree of stretch. Changes, occurring within or outside the body, that affect nervous system functioning.
