What is the significance of the pupil's size in vision?

Back

The size of the pupil regulates the amount of light entering the eye, affecting brightness and clarity of the image.

Front

What are the different types of joints in the human body?

Back

There are several types of joints, including hinge joints (like the elbow), ball-and-socket joints (like the shoulder), and pivot joints (like the neck).
