Part of a neuron that receives a stimulus

What are dendrites?

Part of a neuron that carries messages away from the cell

What is an axon?

Substance released by axon terminal that triggers a nerve impulse

What is a neurotransmitter?

Point at which an impulse from one nerve cell is communicated to another nerve cell

What is synapse?

Axons covered with this material appear white and conduct impulses faster than axons not covered with this material

What is the myelin sheath?

Division of the nervous system that consists of brain and spinal cord

What is the CNS or central nervous system?

Division of the nervous system that consists of cranial and spinal nerves

What is the PNS or peripheral nervous system?

Division of the nervous system that is not under voluntary control and includes sympathetic and parasympathetic nervous systems

What is the autonomic nervous system?

Division of the PNS that is under voluntary control

What is the somatic nervous system?

Division of the autonomic nervous system that is known as “rest and digest”

What is the parasympathetic nervous system?

In a reflex arc, muscles and glands are known as ________.

What are effectors?

Sensory neurons are also called _________ neurons.

What is afferent?

Motor neurons are also called __________ neurons.

What is efferent?

The first step in a reflex arc, could be sense organs.

What are receptors?

Middle step in a reflex arc, between afferent and efferent neurons

What is the integration center?

LOBE of the brain that is associated with memory, emotions, and decision- making, contains primary motor cortex

What is the frontal lobe?

LOBE of the brain that integrates sensory information and spatial awareness

What is the parietal lobe?

Part of the brain that regulates temperature, thirst, hunger and other drives

What is the hypothalamus?

Deep groove that divides the frontal and parietal lobes

What is the central sulcus?

Large fiber tract that joins the two cerebral hemispheres and allows communication between them

What is the corpus callosum?

LOBE that processes, integrates and interprets visual information

What is the occipital lobe?

LOBE for hearing, language and speech

What is the temporal lobe?

Groove that separates the two cerebral hemispheres

What is the longitudinal fissure?

Part of the brain stem that regulates breathing

What is the pons?

Areas in the frontal and parietal lobes that are essential in speech

What are the Broca’s and Wernicke’s areas?

Ion that rushes into the cell during depolarization

What is sodium?

Gates that are responsible for repolarization (2)

What are sodium inactivation and potassium gates

5 steps of an action potential in order

What are: stimulus, threshold potential, depolarization, repolarization and undershoot

Cell’s resting membrane potential

What is -70 mv

The sodium potassium pump actively transports this many K+ into the cell and this many Na+ out of the cell

What are 2 and 3?

List 3 parts of the diencephalon.

FINAL JEOPARDY ANSWER Epithalamus, thalamus, hypothalamus, pituitary gland (others possible)
