The two macronutrients involved in nerve action are carbohydrates and fats, both of which serve as essential energy sources for the brain and nervous system. They are metabolized to produce ATP, which fuels nerve impulse transmission and neurotransmitter release. Additionally, both macronutrients contribute to the maintenance of cell membrane integrity, which is crucial for proper nerve function. Their interplay ensures efficient communication within the nervous system.

What are the factors involved in the transmission of a nerve impulse?
action potational. volage change, threshold etc
Action potentials are conducted from the baroreceptors to the brain via the phrenic nerve?
Action potentials from baroreceptors are transmitted to the brain primarily through the glossopharyngeal nerve (cranial nerve IX) and the vagus nerve (cranial nerve X), not the phrenic nerve. The phrenic nerve primarily innervates the diaphragm and is involved in motor control of respiration. The baroreceptors detect changes in blood pressure and relay this information to the cardiovascular centers in the brainstem for regulation of heart rate and blood pressure. Thus, the phrenic nerve is not involved in the baroreceptor signaling pathway.
What cranial nerve is involved in Bell's palsy?
The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
What is the cranial nerve supplies motor action to the muscles of mastication?
The cranial nerve that supplies motor action to the muscles of mastication is the mandibular branch of the trigeminal nerve, also known as cranial nerve V3. This nerve innervates the major muscles involved in chewing, including the masseter, temporalis, and pterygoid muscles. It plays a crucial role in the process of mastication by facilitating jaw movement.
What nerve is involved when one is said to have bumped their funny bone?
The ulnar nerve is the nerve involved when one is said to have bumped their funny bone. This nerve also is involved with the movement of the lower parts of the arm.
What cranial nerve is involved in hyper extending and flexing the neck?
The spinal accessory nerve (cranial nerve XI) is involved in hyperextending and flexing the neck. This nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in these movements.
What part of the nervous system is affected by the bell's palsy?
The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
Which cranial nerve is involved in cacial paralysis?
The Vagus nerve
What is a nerve emerging from the cervical plexus involved in breathing?
The Phrenic Nerve
Is a action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Is an action potential necessary for a nerve impulse to occur?
Yes, an action potential is needed for a nerve impulse to occur.
Nerve commonly involved in guillain barre syndrome?
It's Facial nerve (7 cranial nerve)
