Exam 9: Nervous System

Faster impulse conduction speeds are possible with _______ axons.

In the patellar reflex the afferent and efferent pathways are part of the femoral nerve,so the femoral nerve is

The reticular formation

Which describes the ion concentrations inside and outside of a neuron?

Sensory and motor function,memory,reasoning and other higher cognitive functions are performed by this part of the brain.

Dorsal roots of spinal nerves are

When the measured potential of a membrane reaches threshold,

A nerve is a single neuron.

This motor branch of the peripheral nervous system controls skeletal muscle.

Sensory nerves carry information to effectors.

If fibers in an ascending tract of the spinal cord are cut,the affected person will have a loss of motor functions below the injury.

A _____________ is defined as a rapid automatic response to a stimulus.

These neuroglia form an epithelial-like membrane that lines the enclosed spaces of the brain and spinal cord.

This condition is caused by unequal distribution of positive and negative charges across the plasma membrane of a neuron.

When ten or more neurons conduct impulses to five or fewer same post-synaptic neurons,the conduction pattern is said to be

In most neurons,the threshold potential is about

The gray commissure of the spinal cord surrounds the central canal.

Basal nuclei produce dopamine and function with other brain areas to

Effectors that are capable of bringing about change in the internal environment include muscles and __________.

Astrocytes provide structural support in the nervous system.
