Looking at a standing human, what is the line that demonstrates the body's bilateral symmetry?
a. facing the side and drawing a line up and down the center of the body
b. facing the front and drawing a line up and down the center of the body
c. facing the front and drawing a line side to side across the middle of the body
d. facing the top of the head and drawing a line across the head touching each ear

The correct answer is option B.

Explanation:

Human body has bilateral symmetry in them. The bilateral symmetry means that the body can be divided into exact same halves if a line is drawn down the center. Bilateral symmetry can be demonstrated in humans by facing towards the front and make a lineup and down the center of the body.

Bilateral symmetry creates a mirror image in the body by dividing it in right and left plane. It may assist your brain to understand make visual perception easier and if body is in different positions and.

Thus, the correct answer is option B.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
