Let's briefly discuss the peripheral nervous system.
00:04
So the peripheral nervous system is made up of both nerves and ganglia.
00:09
And nerves are cable -like bundles of axons that make up the majority of the peripheral nervous system tissues.
00:18
The nerves are generally classified on the basis of the direction in which they carry nerve impulses.
00:25
And they can be classified as sensory, motor, or mixed.
00:30
Nerves and we're going to focus on these sensory nerves.
00:34
So sensory nerves transmit information from sensory receptors in the body to the central nervous system.
00:42
And they're also called afferent nerves.
00:46
And if we were to draw that, so up here, here's our skin, and we'll draw the nerves blue.
00:56
So we have many little nerve endings.
01:01
And here.
01:02
Here's our afferent nerve.
01:06
And over here we have our spinal cord...
