Exam 27: Communication and Control 1: the Nervous System

The brain and the spinal cord make up the central nervous system (CNS).

If the left side of the body is paralyzed by a stroke or other brain injury, the damage occurred on the left side of the brain.

Match the following. A) bundle of axons B) carries signals away from the CNS C) glial membrane wrapping D) carries signals to the CNS E) mostly neuron cell bodies -Nerve

Match the following. A) bundle of axons B) carries signals away from the CNS C) glial membrane wrapping D) carries signals to the CNS E) mostly neuron cell bodies -Gray matter

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

Voluntary movement of the legs is controlled by the somatic nervous system.

Match the following. A) bundle of axons B) carries signals away from the CNS C) glial membrane wrapping D) carries signals to the CNS E) mostly neuron cell bodies -Myelin

When a neuron is resting, it has a higher concentration of Na⁺ ions inside the cell membrane than outside.

Any nerve that carries messages from the brain and spinal cord is an afferent division of the PNS.

The parasympathetic division of the autonomic nervous system would be key in preserving an individual who is escaping from a dangerous situation.

Damage to the medulla oblongata in the brain could interfere with breathing.

Our visual system creates images as well as perceiving them.

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

Neurons are not true cells because they aren't spherical in shape.

Different parts of the tongue are responsive to different tastes.

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

Match the following. A) bundle of axons B) carries signals away from the CNS C) glial membrane wrapping D) carries signals to the CNS E) mostly neuron cell bodies -Afferent neuron

The human body has more sensory input to the CNS than the traditional "five senses."

Match the following. A) bundle of axons B) carries signals away from the CNS C) glial membrane wrapping D) carries signals to the CNS E) mostly neuron cell bodies -Efferent neuron

A nerve is larger than a neuron.
