Who is known as the 'Father of Genetics'? Mendel
List 4 of the 7 minor senses. Touch, taste, smell, pain, heat, cold, pressure
What are the two components of the Central Nervous System? Brain and spinal cord
What determines how bad a spinal cord injury is? The extent of the damage, location, swelling, and whether or not the cell body dies
Why are spinal cord injuries so dangerous? When the spinal cord gets severed, it cannot repair itself and all feeling and control is lost below the break.

List 2 parts of the middle ear. Hammer, anvil, and stirrup (malleus, incus, and stapes
List 2 of the meninges (covering of the brain). Dura mater, pia mater, and arachnoid membrane
Explain what happens with your olfactory receptors when you walk into and stay in a room that has a bad odor. They become accommodated and stop sending the signal to you brain--you no longer detect the odor
Why does a person sometimes like the taste of things as they get older that they strongly disliked when they were younger? Taste buds are damaged or die and are not reproduced as much as you get older; fewer taste buds mean less ability to distinquish tastes
Why do we have either good night vision or good color vision? You have a limited number of rods and cones; more cones means better color vision but you will have fewer rods for night vision and vice versa.
Explain how negative feedback loops work. React to a change outside of regular ranges for homeostasis and generate an opposite response to return the body to acceptable ranges.
