Sheep Eye Dissection Analysis

The lens of the eye is used to focus on objects at various distances. Some of the vitreous humor is surrounding the lens. The vitreous humor helps refract light.

. 

The opening is the pupil and the surrounding brownish layer is the iris. The pupil controls how much light enters the eye and the iris controls how big the pupil is The black layer is the ciliary body which helps stretch the lens in order to focus better on different objects. 

The transparent part is the cornea and the surrounding grey part is the sclera. The cornea allows light into the eye and helps with refraction and the sclera helps keep the shape of the eye ball.

The retina is the clear and thin gel layer and helps processes the image from the lens. The bluish and greenish part is the choroid. This part of the eye provides nourishment.

The Clay Brain

In this activity we modeled the left hemisphere at the sagittal plane and the right cerebral hemisphere at the lateral view. The different parts are labeled and different colors were used to show the relative size and area of the part. 

The Woman with a hole in her brain

A woman had trouble walking and felt nauseous. When she entered a hospital, it was discovered that she was missing cerebellum. The cerebellum controls voluntary movement as well as balance. It made sense that the woman felt these symptoms throughout her life, but it was miraculous that how minor they were. Her case shows how the brain how the brain can adapt and compensate for missing functions.

If the brain's Brocca's area is responsible for language and speech production. If someone were missing this area, they would not be able to produce speech. They could still survive without it and still be able to understand speech. The Wernicke's area can partially compensate by helping the person understand and process speech.
