Exam 9: Nervous System

Neurotransmitters that move the post-synaptic membrane potential closer to threshold are

When an impulse jumps from node to node along a myelinated axon,the conduction is termed

Brain damage to the temporal lobe,where recent memory is processed,can result in the inability to form long-term memory.

The cells in the nervous system that fill spaces and give support to neurons are called _____________.

Bundles of axons that carry impulses from the central nervous system to effectors are

The phrenic nerves arise from the

Cranial nerves connect the brain only to head and neck regions;spinal nerves connect all regions below the neck.

If a neuron's membrane potential measures +25mV,the neuron is

The difference in electrical charge between the inside and outside of a resting nerve cell membrane is called the resting membrane ______________.

When you raise your hand to ask a question in class,your brain sends an impulse to your deltoid muscle by way of

Cerebrospinal fluid is found in this location.

This part of the brain contains centers that coordinate voluntary muscle movement.

The pressure of cerebrospinal fluid is usually measured by introducing a hollow needle between lumbar vertebrae into the

The peripheral nervous system includes sensory and motor divisions.

The part of the brain that coordinates voluntary muscle movements is the

During an action potential,depolarization occurs as a result of

A neuron may release more than one type of neurotransmitter.

Sympathetic tone is defined as ongoing stimulation of smooth muscles in the walls of blood vessels,which results in partial constriction.

The interconnected fluid-filled cavities in the brain are called ______________.

When a neuron increases its release of neurotransmitter in response to a nerve impulse,as a result of repeated stimulation,it is said to be
