So we are trying to label the external anatomy of a grasshopper.
00:05
The first thing we can do is label the three section of the insect's body.
00:09
So that will be a, e, and g.
00:11
So let's first look at a.
00:14
So with a, this is the top portion of the body.
00:17
So this is known as the head.
00:22
The middle section of the body is known as the thorax.
00:31
And the back portion of the insect's body is known as the abdomen.
00:36
Them.
00:43
All right.
00:44
So the next thing we will do is label the parts in each section.
00:48
So let's start off in the head section.
00:51
So that will be with b, c, and d.
00:54
So with b, grasshoppers have a pair of antennas that are jointed and they're used to sense their environments.
01:02
So where b is are the antennas.
01:09
And then located on the face, they have two compound eyes.
01:14
So that is where d is.
01:24
Now there's a simple eye located in the center of the forehead.
01:29
This is just used to detect light.
01:32
So that is where c is.
01:36
Simple eyes.
01:39
And that completes our head section...
