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 white outer covering of the eyeball‚ which we later discovered to be known as the sclera. We also noticed the blue covering over the front of the eye‚ known

symptoms. His increased heart rate started when the cardioacceleratory center in the Medulla oblongata sent impulses down the spinal cord to the preganglia and ganglionic neurons of the Cervical and T1-T3 spinal cord segments‚ then the cardiac and pulmonary plexuses‚ which then leads to the heart and increases the rate at which it pumps. At the same time‚ his respiratory rate increased similarly. Impulses sent down his spinal cord through the preganglia and ganglionic neurons of the Cervical and T1-T3 spinal

Positively and negatively charged particles should be equal. http://www.nlm.nih.gov/medlineplus/ency/article/002350.htm Electrolytes are minerals in your blood and other body fluids that carry an electric charge. Electrolytes are charged particles in body fluids that help transmit electrical impulses for the proper functioning of the heart‚ nerves and muscles. The number of positively charged

Submucesa—loose connective tissue‚ glands‚ blood vessels‚ lymphatic vessels‚ and nerves. c. Muscular layer—two coats of smooth muscle tissue. d. Serosa or serous layer—epithelium on the outside and connective tissue beneath. 4. Distinguish between mixing movements and propelling movements. A mixing movement is a wavelike motion

thought‚ reason‚ emotion‚ and memory. III. Nervous System: 1. The nervous system of the human being is responsible for sending‚ receiving‚ and processing nerve impulses throughout the body. All the organs and muscles inside your body rely upon these nerve impulses to function. 2. The nervous system consists of two major divisions of nerves‚ 1. Central nervous system- which controls; the functions of the brain and spinal cord. 2. Peripheral nervous system- which controls all other neural elements
