Exam 8: The Nervous System: Structure and Control of Movement

Sympathetic neurons are motor neurons,and parasympathetic neurons are sensory neurons.

The ______________________ is an organ located in the inner ear and is responsible for maintaining general equilibrium.

Relative to brain health,regular aerobic exercise has been shown to

The motor cortex is concerned with voluntary movement and is located within the

Nerve fibers that carry impulses toward the central nervous system are called

Repeated sport-related traumatic brain injuries (i.e. ,concussions)are associated with a higher risk of developing_________.

Neurons are negatively charged on the inside of the cell with respect to the charge on the exterior of the cell.This electrical charge difference is called

The summing of many excitatory post-synaptic potentials (EPSPs)from a single pre-synaptic neuron over a short time period is called

The Golgi tendon organs monitor

The joint receptors that provide the central nervous system with information about body position are called

Muscle spindles provide sensory information relative to the

The resting membrane potential of neurons is determined by

The mechanism responsible for the size principle is that compared to large motor neurons,

Which of the following statements are true about muscle chemoreceptors?

Nerve fibers that conduct impulses away from the central nervous system are called

The action potential is generated when an excitatory stimulus

Exceptions to the size principle exist during the performance of high intensity and short duration exercise.This recruitment of fast motor units before activation of slow fibers can be achieved by

The area of the brain that aids in control of movement and may initiate fast ballistic movements is the

The ability of a neuron to respond to a stimulus is termed

Voluntary movements are planned and executed by the motor cortex without outside influence from other areas of the nervous system.
