front 1 nervous system | back 1 the master controlling and communicating system of the body |
front 2 sensory imput | back 2 gathered information |
front 3 integration | back 3 the nervous system processes and interprets sensory input and decides what should be done at each moment |
front 4 motor output | back 4 nervous system causes a response called motor output by activating effector organs - the muscles and glands |
front 5 effector organs | back 5 (Glandular or Muscle) receive or respond to Autonomic Nervous System (ANS) signals. Cardiac and smooth muscle, glandular tissue. Ex: Adrenal, Medulla |
front 6 central nervous system consists of what | back 6 the brain and the spinal cord |
front 7 peripheral nervouse system consists of | back 7 nerves (bundles of axons) |
front 8 spinal nerves do what | back 8 carry imipulses to and from the spinal cord |
front 9 cranial nerves do what | back 9 carry impulses to and from the brain |
front 10 What part of the eye is called "the white of the eye"? Is it A) the sclera or B) the choroid? | back 10 the sclera. This opaque outer layer appears white due to the presence of collagen fibers. |
front 11 which layer is the retina found? Is it the A) uvea or B) neural layer? | back 11 the neural layer. The retina contains the neural cells whereas the uvea contains the iris |
front 12 Which iris color has more melanin? Is it A) green or B) blue? | back 12 A) green. Color variation is due to concentration and distribution of melanocytes. Blue has the least amount of melanin. |
front 13 What are the protein fibers called that make up the lens? Are they A) collagens or B) crystallins? | back 13 crystallins. Collagen is important in the connective tissues and cornea. Crystallins appear in a precisely packed pattern in the lens. |
front 14 What do we call the gel-like substance in the posterior chamber of the eyeball? Is it A) the aqueous humor or B) the vitreous body? | back 14 B) the vitreous body. The aqueous humor is the fluid in the anterior chamber. |
front 15 Which photoreceptor cells are responsible for sharp vision? Is it A) the rods or B) the cones? | back 15 B) the cones. The cones are stimulated by color and intense light. |
front 16 Which neural cells regulate action potential generation in the eye? Is it A) the ganglion cells or B) the bipolar cells? | back 16 the bipolar cells. They regulate action potentials of the ganglion cells based on stimulation of the rods and cones |
