Exam 27: Communication and Control 1: the Nervous System

Most sensory information is routed through which structure before arriving in the cerebrum?

The cilia that respond to sounds in the cochlea have "trapdoor" channels for K+ ions.

Which part of the brain is probably most involved with dreaming?

Which of the following does the central nervous system use for the action of pulling your hand away from a hot object?

The action potential moves across the synaptic cleft as an electrical signal.

The cochlea is part of the:

The neuron being stimulated by a neurotransmitter comes after the synaptic cleft.

A person is diagnosed with a brain tumor that is treated with radiation.The treatment is successful,but the doctor believes some brain damage occurred.The patient is constantly complaining of being thirsty,even though she has had plenty of water to drink.Which part of the brain is damaged in this patient and why?

The term "brain dead" may refer to the fact that all brain centers have ceased to function except the:

Spinal nerves emerging from the spinal cord are named for:

Which of the following best describes sensory receptors?

An organ or group of cells that responds to a motor neuron is a/an:

The basic taste sensations are different in that each sensation works through:

A nerve is larger than a neuron.

Our "oldest" sense,which works in a very similar way in insects,is the sense of:

Proprioceptors provide us with:

Humans have sophisticated,highly evolved brains that would be useful in directing all body activities.Yet we have the autonomic division and reflexes that intentionally bypass the conscious centers of the brain and directly handle some responses.Evaluate why this is useful.Also,propose situations to the contrary in which it might be useful to use the brain rather than an autonomic response,and explain why we respond as such anyway.

Cells in the central nervous system that are important for functions such as memory are the:
