Which experiment would most likely contain experimental blas?

Mixed cranial nerves containing both motor and sensory fibers include all except which of the following?

Fed [463]

Answer:

Answer is option D.

Olfactory nerve is a sensory cranial nerve.

Explanation:

Nerves are the part of peripheral nervous system, which transmit signals from brain or spinal cord (central nervous system) to the different parts of the body and vice versa.

Based on the direction of signal transmission, they are classified into three groups; sensory nerves (afferent nerves) pass signals from sensory receptors (pain, pressure, temperature etc) in various parts of the body to the central nervous system, motor nerves (efferent nerves) transmit signals from the central nervous system to the muscles and glands all throughout the body, mixed nerves contain both sensory and motor fibers which conduct both sensory information and muscle commands throughout the body.

Based on where they are connected to the central nervous system, they are classified into two groups; spinal nerves connected to the spinal cord and cranial nerves attached to the brain. All the 31 spinal nerves are combined sensory and motor axons.

Of the 12 cranial nerves, three are sensory nerves, four are motor nerves and five are mixed nerves. The sensory cranial nerves are olfactory (smell), optic (vision) and acoustovestibular (hearing and balance) nerves. The motor cranial nerves are trochlear (controls the superior oblique muscle of the eyeball), abducens (controls the lateral rectus muscle of the eyeball), accessory (controls the trapezius muscle in the back and shoulders), hypoglossal (controls the muscles of the throat and helps in swallowing) nerves. The five mixed cranial nerves are occulomotor, trigeminal, facial, glossopharyngeal and vagus nerves.

A soldier is preparing to enter an area in which there is a high risk for chemical exposure to a nerve agent. What should the so

goldenfox [79]

Answer:

Injections that contain 2 mg atropine and 600 mg pralidoxime chloride.

Explanation:

The chemical exposure with the nerve agent can cause drastic health related problems in the soldier's body. The soldiers should given proper medications before entering in the risk areas.

The entering of soldiers in the chemical exposure should be given 2 mg atropine and 600 mg pralidoxime chloride. These are known as Mark I automatic injectors. Diazepam can also be administered in the partner.

if you were to watch an individual neurotransmitter molecule just after it was released what would happen to it

Olenka [21]

Neurotransmitter leaves the presynaptic cell by exocytosis. It is released in the synaptic space, and moves to the postsynaptic membrane to meet its receptor. When binding occurs, it triggers a response in the new cell.

-----------------------------------------

Every neuron forms connections with another cell.

When a presynaptic cell sends information, a neurotransmitter is released.

After the exocytosis event, this chemical substance travels through the synaptic space forward to the other cell. Once there, it binds to its receptors in the postsynaptic membrane.

When the joining occurs, the receptor acquires a channel shape. This change allows the ion transference that will make possible the modification of the action potential.

This binding produces the excitatory postsynaptic potential -depolarization-.

A new action potential initiates in the postsynaptic cell and spreads to the rest of the membrane, depolarizing it.

If the communication between cells needs to stop, the neurotransmitter will be taken out from the synaptic space <em>instead of binding to its receptor. </em>

There are two mechanisms by which the neurotransmitter can be eliminated: by deactivation or reuptake.

In which phase of the cell cycle do cells grow and synthesize new proteins and organelles?

Kazeer [188]

G1 phase is the phase of the cell cycle that cells grow and synthesize new proteins and organelles.

G1 phase is the phase between the completion of the mitosis and the beginning of the DNA synthesis in the S phase. In this phase, protein synthesis and production of organelles happen.
