Ch 8: Structural Divisions Flashcards
The Nervous System
What are the two STRUCTURAL divisions of the nervous system?
- Central Nervous System (CNS)
- Peripheral Nervous System (PNS)
What makes up the central nervous system?
- Brain
- Spinal Cord
What makes up the peripheral nervous system?
All nerves outside the CNS
What do cranial nerves do?
Cranial nerves carry impulses to and from the brain
What do spinal nerves do?
Spinal nerves carry impulses to and from the spinal cord
The brain and spinal cord make up which STRUCTURAL division of the nervous system?
Central Nervous System (CNS)
Nerves that carry impulses to and from the brain
Cranial nerves
Nerves that carry impulses to and from the spinal cord
Spinal nerves
All nerves outside the CNS are contained in which STRUCTURAL system?
Peripheral Nervous System (PNS)
What are the two FUNCTIONAL divisions of the nervous system?
- Somatic Nervous System
- Autonomic Nervous System (ANS)
The autonomic nervous system (ANS) can be further broken down into what two groups?
- Sympathetic Nervous System
- Parasympathetic Nervous System
What is another name for the somatic nervous system?
Voluntary Nervous System
What is the somatic nervous system?
Nerve fibers that connect the CNS with structures of the body such as skeletal muscles and the skin
What is another name for the Autonomic Nervous System (ANS)?
Involuntary Nervous System
What is the function of the Autonomic Nervous System?
Fibers that connect the CNS with glands that form secretions, organs that contain smooth muscle, and the cardiac muscle of the heart
What makes up the Peripheral Nervous System (PNS)?
All nerves outside the Central Nervous System (CNS)
The somatic nervous system and the autonomic nervous system (ANS) are parts of which main division of the nervous system?
FUNCTIONAL Division
The central nervous system (CNS) and the peripheral nervous system (PNS) are parts of which main division of the nervous system?
STRUCTURAL Division
The sympathetic nervous system and the parasympathetic nervous system are divisions of what FUNCTIONAL division?
Autonomic Nervous System (ANS)
What is another name for the Voluntary Nervous System?
Somatic Nervous System
“Nerve fibers that connect the CNS with structures of the body such as skeletal muscles and the skin” describes which FUNCTIONAL division?
Somatic Nervous System
What is another name for the Involuntary Nervous System?
Autonomic Nervous System (ANS)
“Fibers that connect the CNS with glands that form secretions, organs that contain smooth muscle, and the cardiac muscle of the heart” describes which FUNCTIONAL division?
Autonomic Nervous System (ANS)
What is the Sympathetic Nervous System?
The emergency nervous system that takes control in stressful situations.
