Nervous System Key Terms

Sympathetic

• Consists of nerves and has two divisions: somatic nervous system and autonomic nervous system.
• usually works with sympathetic nervous system to maintain homeostasis in the body and to control in
• Carries messages between the CNS and the body
• usually works with parasympathetic nervous system to maintain homeostasis in the body and to control in

Parasympathetic

• usually works with parasympathetic nervous system to maintain homeostasis in the body and to control in
• Consists of nerves and has two divisions: somatic nervous system and autonomic nervous system.
• usually works with sympathetic nervous system to maintain homeostasis in the body and to control in
• Carries messages between the CNS and the body

Autonomic Nervous System

• Carries messages between the CNS and the body
• Contains the sympathetic and parasympathetic nervous system which work together to control involuntary body functions.
• Consists of the brain and spinal cord.
• Consists of nerves and has two divisions: somatic nervous system and autonomic nervous system.

Central Nervous System (CNS)

• Consists of the brain and spinal cord.
• Contains the sympathetic and parasympathetic nervous system which work together to control involuntary body functions.
• Carries messages between the CNS and the body
• Consists of nerves and has two divisions: somatic nervous system and autonomic nervous system.

Peripheral Nervous System

• Contains the sympathetic and parasympathetic nervous system which work together to control involuntary body functions.
• Carries messages between the CNS and the body
• Consists of the brain and spinal cord.
• Consists of nerves and has two divisions: somatic nervous system and autonomic nervous system.

Somatic Nervous System

• Contains the sympathetic and parasympathetic nervous system which work together to control involuntary body functions.
• Consists of the brain and spinal cord.
• Carries messages between the CNS and the body
• Consists of nerves and has two divisions: somatic nervous system and autonomic nervous system.

Brain

• Located between the cerebrum and midbrain. Contains the thalamus and hypothalamus.
• Mass of nerve tissue well protected by membranes and the cranium or skull.
• Section of the brain below the cerebrum that is responsible for muscle coordination, balance, posture and muscle tone.
• Largest and highest section of the brain. arranged in folds and separated in to lobes. Responsible for reasoning, thought, memory, judgement, speech, sensation, sight, smell, hearing and voluntary body movement.

Cerebellum

• Section of the brain below the cerebrum that is responsible for muscle coordination, balance, posture and muscle tone.
• Mass of nerve tissue well protected by membranes and the cranium or skull.
• Located between the cerebrum and midbrain. Contains the thalamus and hypothalamus.
• Largest and highest section of the brain. arranged in folds and separated in to lobes. Responsible for reasoning, thought, memory, judgement, speech, sensation, sight, smell, hearing and voluntary body movement.

Diencephalon

• Mass of nerve tissue well protected by membranes and the cranium or skull.
