sympathetic

The branch of the autonomic nervous system that prepares the body for quick action in an emergency is the __________ division.

. the central nervous system and the peripheral nervous system

The nervous system is comprised of two major parts: __________.

. the nervous system

. The system that relays messages in the form of electrochemical impulses throughout the body is called __________.

sympathetic and parasympathetic

The autonomic nervous system has two divisions: __________.

peripheral

All nerve cells and fibers that are NOT in the brain or spinal cord make up the __________ nervous system.

efferent neurons

Neurons whose primary purpose is to carry messages from the spinal cord or the brain to the muscles and glands are called __________.

sympathetic

The branch of the autonomic nervous system that prepares the body for quick action in an emergency is the __________ division.

sensory neurons

A young woman returns from a day at the beach to find she has developed a severe sunburn. Which neurons are sending the messages from her burned skin to her brain informing her of the pain from the burn?

. peripheral nervous

The division of the nervous system that connects the brain and spinal cord to the rest of the body is the __________ system.

central and peripheral nervous systems.

The FIRST division of the nervous system consists of the:

peripheral

The autonomic and somatic nervous systems are divisions of the _______ system.

. autonomic nervous system.

The part of the nervous system that allows the brain to regulate digestion, heart rate, and respiration without our conscious attention is the:

. parasympathetic; sympathetic

Calm is to aroused as _______ is to _______.

autonomic nervous system.

The parasympathetic and sympathetic divisions make up the:

. brain and the spinal cord

The central nervous system consists of the __________.

brain and spinal cord.

The two major divisions of the central nervous system are:

axon

A long structure leaving the cell body that action potential travel along is called the __________.

the biological basis for human behavior

Physiological psychologists study __________.

dendrites

The short fibers which extend from the neurons allowing it to receive messages from other neurons are

axon

The part of the neuron that carries outgoing messages either to another neuron or to a muscle or gland is the

cells that send and receive information.

Neurons are:

. carry messages away from a cell body.

cells that send and receive information.

. helps to speed up neural messages within the cell.

The myelin sheath

neurons.

The basic message-carrying cells of the nervous system are labeled:

neurons.

Specialized cells in the brain which send and receive information are called:

coordinates actions so that movements are efficient

The cerebellum __________.

the left hemisphere

Which hemisphere of the cerebral cortex is usually dominant in language tasks?

the temporal lobe.

The part of the brain which controls hearing, does some additional processing of visual information, and is probably the site of permanent memory storage is:

corpus callosum

The structure that connects the two hemispheres of the cerebral cortex is the

. brainstem.

The medulla, pons, and thalamus are all part of the:

parietal

The somatosensory cortex is located in the _______ lobe of the brain.

frontal

The motor cortex is located in the _______ lobe of the brain.

medulla.

The part of the brain which controls breathing, heartbeat, and posture is the

breathe.

. Damage to the medulla can seriously impair one's ability to

all of the above

The spinal cord:

coordinates actions so that movements are efficient

The cerebellum __________.

. thalamus

. The structure in the center of the forebrain that relays sensory information is called the __________.

corpus callosum

The structure that connects the two hemispheres of the cerebral cortex is the _________.

connects the left and right cerebral hemispheres.

The corpus callosum:

the right side of the body.

The left cerebral hemisphere primarily controls

. the left side of the body.

The right cerebral hemisphere primarily controls:

. spinal cord.

The brain is connected to the rest of the body via the:
