1. 5/9 points Match each neurological term to its meaning. (Two answers are not used.) when the inside of the neuron becomes more positive than the resting potential depolarization depolarization a large depolarization that carries an electrical signal along the axon action potential action potential covers the axon and makes electrical conduction more rapid myelin sheath myelin sheath ions that enter the neuron and initiate electrical conduction along the axon acetylcholine sodium a neurotransmitter that passes an electrical signal from one neuron to another dendrite acetylcholine a neuronal fiber that conducts an electrical signal toward the cell body sodium dendrite a neuronal fiber that conducts an electrical signal away from the cell body potassium axon the difference between electrical charges on each side of the neuron's membrane membrane potential membrane potential a small space that separates an axon from another neuron synapse synapse 2. 2/2 points What is the function of homeotic genes in animal development? 3. 2/2 points In mammals, hormone signals are required for 4. 2/2 points Which of the following are stem cells that can produce all cell types in the human body? They store information within the cytoplasm of the ovum. They control the process of metamorphosis. They control whether an animal is male or female. They control the development of individual body segments. none of these expression of homeotic genes development of female characteristics of an embryo none of these sex differentiation of both male and female embryos development of male characteristics of an embryo Cells in the bone marrow of an adult. Cells in the testes that normally produce sperm. Cells from the inner cell mass of a blastocyst. all of these Cells in the brain tissue of an adult.
