4 0

Answer:

True

Agents that paralyze skeletal muscle by simple competitive inhibition of acetylcholine at muscle receptor sites are called?
Fed [463]

Agents that paralyze skeletal muscle by simple competitive inhibition of acetylcholine at muscle receptor sites are called?

a. nondepolarizing

b. depolarizing

c. antagonizing

d. repolarizing

Answer:

a. nondepolarizing

Explanation:

As the nerve impulse arrives, the synaptic end bulbs of the motor neurons release acetylcholine in the synapse. Acetylcholine binds to its receptors present at the motor endplate. This results in the opening of an ion channel in the ACh receptor to allow the movement of the Na+ into the cell. This makes the inside of the muscle fiber more positively charged, that is, depolarized.

Depolarization triggers a muscle action potential. Drugs or chemicals that paralyze skeletal muscle by competitive inhibition of acetylcholine at muscle receptor sites are called non-depolarizing as they do not allow the acetylcholine to facilitate the depolarization of the muscle fiber.

Rocky mountain juniper (juniperus scopulorum) and one-seeded juniper (j. monosperma) have overlapping ranges. pollen grains (whi
bixtya [17]

Answer:

Mechanical isolation

Explanation:

mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.

The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.

What is the term for a condition whereby small amounts of urine leak from a bladder that is always full as a result of a spinal
grigory [225]

Answer:

Overflow incontinence

Explanation:

Overflow incontinence is due to the leakage of small amounts of urine out of a bladder that is perpetually full. Diabetes and spinal cord injuries may trigger this kind of incontinence.

A spinal cord injury may disrupt interactions among the nerves in the spinal cord that regulates bladder and bowel function and the brain, which leads to incontinence.

This type of inconsistency results from Injury to the spinal cord at T10-L2 causing an overactive bladder.
