Cow’s eye dissection AIM ~ To locate and distinguish specific parts to an eye of a cow‚ in particular‚ its lens. OBSERVATIONS ~ Before actually beginning the dissection of the cow’s eye‚ we were about to sketch a fairly relative picture of our observing’s of the exterior body of the eye. The eye‚ having almost completely being sheltered in fat and muscle‚ was quite firm and only the cornea and optic nerve was identified. By further cutting down the fat‚ we were able to spot a rather tough pinkie

The skeletal system is made up of cartilage and bone. Both bone and cartilage are connective tissues‚ that is‚ they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells‚ the gelatin the support material for matrix‚ and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances‚ we can produce a material that is very hard like

Rat Dissection Prelab 1. Is your left like your right side? It should be similar to your right but there can be differences like if damage was done to one side or if one side was mutated and disfigured. 2.

Many female snakes (15 of 20 snakes)‚ but few male

Heart Dissection Sheep have a four-chambered heart‚ as do humans. By studying a sheep heart you can learn about your own heart at the same time. 1. Identify the right and left sides of the heart.

If you feel the heart‚ the left half will feel much firmer and more muscular than the right side. The left side of the heart has to
