In this very small unit, we dissected an eyeball of a sheep. First, we took these small scissors ,and cut out the outside of the eyeball which is also known as the fat tissue and sclera. Inside there was a jelly like liquids called aqueous humor and the vitreous humor. This part helps retain the eye's shape. On the other side of the eye is the Iris. Which controls the amount of light that enters the eye.We also cut through the muscles. The muscles are the superior oblique, rectus, inferior oblique, lateral ,and the medial. Those parts of the eye move the eye up and down ,and side to side. We then took out the lens. It is a pearl like substance that was cloudy because the animal was dead. Then, we spotted the blue like substance that was the 'night vision' of the sheep. Located at the back of the eye, is the optic nerve. This receives images from the retina and sends it to the brain as an electrical impulse. Then there was nothing else to see, so we were done. The end.

There are 6 main parts to a neuron: the cell body, or soma, nucleus, dendrites, axon, myelin sheath, and axon terminals. Neurons send messages throughout the body, with one neuron's axon terminals- which puts out information to another neuron's dendrites- which receives information through a connection called"synaps." The dendrites are connected to the cell body. At the center of the cell body is the nucleus. From the nucleus, the information travels through the axon, which is protected by the myelin sheath. Then it travels out of the axon terminals to the next neuron's dendrites. Eventually, the information will get to the brain, which in turn will make use of the information.

The Nervous system is made of the brain, spinal cord, and the nerves. The nerves are made of Neurons and the Neurons transmit signals from the sensory organs to the brain. Then the brain sends messages to the muscles which make us move or do things. by: Macie 3D Models of the Brain
