Week Three Worksheet Cody Mulock PSY 340 October 27‚ 2014 Teralyn Sell Week Three Worksheet 1. Describe why humans have a blind spot: a. Humans have a blind spot because the spot that the axons meet to form the optic nerve does not have any sensor cells. 2. Describe the functional and anatomical differences between rods and cones: a. Rods: Respond to faint light and are more abundant in the periphery of the eye. Cylindrical shape‚ similar to a welding rod. b. Cones: Responsible for color vision

changes that underlie learning and memory. This occurs when the synapse is active and the postsynaptic cell is depolarized. Cells that lead to the synapse onto the dentate granular cells are called DG cells which then send axons to CA3. CA3 cells are responsible for sending axons to CA1 output cells. LTP has four crucial steps to making the process obtainable. One glutamate the neurotransmitter to the CNS is released allowing acts on both AMPA and NMDA receptors. Sodium receptors are then able to flow

SPECIALIZED CELL ANIMAL Sperm cells PLANT Xylem cells are specialised to find a female cell (egg cells) and join with it. They have tails‚ that makes them move in water to find and fertilize the female cell. They can move because they have many mitochondria located between the tail and the head‚ which gives them energy. In the head‚ there is a vacuole filled with acrosome‚ which is a specialized Lysosome that releases enzymes in order for the Sperm Cell to break into the Egg Cell‚ through

The Reproductive System What is it? The reproductive system is a collection of organs that work together for the purpose of producing a new life The major organs of the reproductive system include the external genitalia and internal organs‚ including gonads that produce gamete‚ which is a cell that fuses with another cell during conception in organisms that reproduce sexually. Substances such as fluids‚ hormones‚ and pheromones are also important to the effective functioning of the reproductive

1. Discuss the relationship between distribution of muscle fiber type and performance. How might exercise training modify or change a person’s fiber-type distribution? Skeletal muscles contain multiple fiber types that are distinguished by their different myosin ATPase speed‚ and the development of their SR. The two main fiber types are type I and type II fibers. Type II fibers have a faster ATPase and a more developed SR than type I fibers. Type II fibers are also part of a larger motor unit‚

of neuron that is specialized to receive information Axon – transmits information away from the soma to other neurons/muscles/glands Action potential – brief period where channels open and it changes chemical reaction within cell Absolute Refractory Period – minimum length of time after an action potential during which another action potential cannot begin All or None Law – either fires or doesn’t fire (activating or not) Thicker axons -- more rapid than thinner Two neurons never touch Seizure
