while a neuron membrane is depolarizing its __________.

Answers

Given what we know about the depolarization of neurons, we can confirm that while a neuron membrane is depolarizing its sodium gates are fully open.

Throughout the human body, sodium is often used to cause shifts in membrane potentials, as well as a variety of other metabolic processes, due to the electric charge of this ion. One such example is the neuron, which uses a flood of sodium ions to depolarize its membrane.

During depolarization, the membrane potential changes from a negative charge to that of a positive one. This is caused by the rapid flooding of sodium into the cell, which increases the positive charge in the interior of the cell and thus affects the membrane's potential.

Answers

A goniometer measures __________..

Answer : A

Explanation : A joint's maximum range of motion

Hope this helps you!

Answer:

A.  a joint's maximum range of motion

Explanation:

A goniometer is a device that is used to measure the maximum arc of motion made by a joint. The traditional goniometer consists of a protractor and two extending arms ,one of the arms is movable while the other one is stationary.To take measurements the center of the goniometer is aligned with the center of a joint. Then the arm of the goniometer is moved until it aligns with the limb that has been moved to a maximum position that the joint allows. The angle made between the two arms of the goniometer is measured in degrees and is the maximum range of motion of the joint.

Answers

For brief quick movements, which muscle fiber type would you therefore predict to be predominant in these muscles...Fast twitch muscle fiber type.

There are three types of muscle tissue. 1. Cardiac 2. Smooth 3. skeletal muscles. The skeletal muscle are involved in voluntary movements of the body.

Since the player uses her hand in a voluntary way of movement, therefore she makes use of her skeletal muscles.

With regards to the skeletal muscles, there are two types with regards to speed, we have the slow twitch and the fast-twitch.

The fast-twitch muscle fiber aids in fast movement of the body but for shorter periods compared to the slow twitch.
