Which of the following is the best example of the function of the peripheral nervous system?
Control of glands and the muscles of internal organs is a function of the __________ nervous system.
About how many neurons are in the brain?
Name and define the two types of impulses sent through the cranial and spinal nerves of the peripheral nervous system.
The two types are sensory (afferent) impulses, which carry information from sensory receptors in the body to the brain and spinal cord, and motor (efferent) impulses, which carry commands from the brain and spinal cord to muscles and glands.
The __________ nervous system is comprised of the brain and spinal cord.
About how many neurons are in the brain?
Controlling voluntary skeletal muscles is a function of the __________ nervous system.
Which of the following is the best example of the function of the peripheral nervous system?
Controlling voluntary skeletal muscles is a function of the __________ nervous system.
Which of the following best describes the function of the sympathetic nervous system?
Identify the nervous system responsible for calming the body and conserving energy.
Which of the following best describes the function of the sympathetic nervous system?
Identify the nervous system responsible for calming the body and conserving energy.
The parasympathetic nervous system.
Name and define the two types of impulses sent through the cranial and spinal nerves of the peripheral nervous system.
Control of glands and the muscles of internal organs is a function of the __________ nervous system.
Identify and explain how the central nervous system is supported and protected.
Identify the four main divisions of the peripheral nervous system and explain each one’s function.
The four divisions are: (1) the somatic nervous system, which carries sensory information and controls voluntary skeletal-muscle movement; (2) the autonomic nervous system, which regulates involuntary functions such as heartbeat, digestion, breathing, and gland activity; (3) the sympathetic nervous system, which arouses the body for action and uses energy during stress; and (4) the parasympathetic nervous system, which calms the body and conserves energy. The autonomic system consists of the sympathetic and parasympathetic divisions.
The __________ nervous system is comprised of the brain and spinal cord.
Identify the four main divisions of the peripheral nervous system and explain each one’s function.
Identify and explain how the central nervous system is supported and protected.
The brain is protected by the skull and the spinal cord by the vertebral column. Both are covered by three layers of connective tissue called the meninges and cushioned by cerebrospinal fluid. Glial cells support, nourish, insulate, and protect neurons, and the blood-brain barrier helps keep harmful substances away from brain tissue.
