nerves are also called neurons and they transport impulses(messages)
Afferent nerves are those that send impulses from the PNS to the CNS. Efferent nerves send impulses from the CNS to the PNS. So the first goes toward the Central Nervous System and the second goes away from it.
Afferent
Motor or efferent nerves.
They are motor nerves which lead to the diaphragm and the intercostal muscles
The Phrenic & Intercostal nerves.
glands
Electrical impulses telling them to contract or relax.
Sensory nerves carry impulses to the brain (as sights seen, sounds heard, etc.). Motor nerves carry impulses from the brain to cause the body to do things such as move muscles.
Your brain tells the muscle to move by sending electric impulses through your nerves to your muscles.
as the motor nerves carry impulses from the brain to the limbs and muscles numbness or feeling will be reduced or lost and muscle tone will diminish.
An electromyogram (EMG) may also be used to determine the health of nerves and muscles using electrical impulses.
The nervous system carries impulses to and from the brain by way of neurons. The bundles are called nerves. Sensory nerves bring impulses into the spinal cord and brain and motor neuron carry impulses away from the brain and spinal cord to the muscles and glands.
Motor nerves allow the brain to stimulate muscle contraction. A motor nerve is an efferent nerve that exclusively contains the axons of somatic and branchial motoneurons, which innervate skeletal muscles (that ensure locomotion) and branchial muscles (that motorize the face and neck).
· Afferent and efferent divisions are:o Sensory (afferent) Division§ Somatic afferent nerves - carry impulses from skin, skeletal muscles, and joints to the CNS§ Visceral afferent nerves - transmit impulses from visceral organs to the CNSo Motor (efferent) Division§ Transmits impulses from the CNS to effector organs, muscles and glands, to effect (bring about) a motor responseAfferent nerves are the one that carry the information from periphery to central nervous system for further processing. While efferent nerves carry the processed information from central nervous system towards the periphery for action.
