Answer:

C. Decrease a person’s ability to hear because pinnae funnel sound into the ear canal

Explanation:

In mammmals, especially humans, the pinna also known as auricle is a large fleshy cartilage outer structure of the hear which is situated on the lateral aspect of the head. The pinna direct sound waves toward the auditory canal. Although the pinna may direct sound into the auditory canal but this portion of the ear is not vital for hearing.

The only main importance of the auricle is just to capture sound, the most important aspect of the outer ear is the ear canal itself, if the ear canal is not open, hearing will be dampened.

Axons are classified into three major groups called A, B, and C, based on their ____________ . Group A has a conduction velocity

Viefleur [7K]

Answer:

1. Based on their physical features and conduction properties

2. 80m/s to 120m/s

3. Has both sensory fibers and motor fibers

4. Group B conduct at 3m/s to 15m/s

5. Group C conduct at 0.5m/s to 15m/s

6. They generally have low conduction velocity and are polymodal

Explanation:

Axons were know to have different thickness and this differences were thought to relate to the speed at which the action potential could travel. This hypothesis was proved by Erlanger and Gasser.

<h3>What are neurons and what do neurons perform?</h3>

Neurons are the primary functional components of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly convey information over large distances. Although glia primarily support the neurons, they are nonetheless crucial for the proper operation of the nervous system.

<h3>What makes neurons so important?</h3>

Information is transported throughout the human body by neurons. They assist in coordinating all of the vital operations of life by using electrical and chemical signals.

<h3>What three types of neurons are there?</h3>

However, we may say that there are three different types of neurons in the spinal cord, sensory, motor, and interneurons.
