Ch. 7.6 Nervous System
What is the autonomic nervous system?
The autonomic nervous system contains the sympathetic and parasympathetic nervous system.
What is the cerebrum?
The cerebrum is the largest and highest section of the brain.
What is the midbrain?
The midbrain is the section located below the cerebrum at the top of the brainstem.
What is the peripheral nervous system?
The peripheral nervous system consists of the nerves and has two divisions, the somatic nervous system and the autonomic nervous system.
Ventricles are hollow spaces that connect with each other and with the space under the arachnoid membrane.
What is the brain?
The brain is a well protected mass of nerve tissue.
What is the diencephalon?
The diencephalon is the section located between the cerebrum and midbrain.
What are nerves?
Nerves are a combination of many nerve fibers located outside the brain and spinal cord.
What is pons?
Pons is the section located below the midbrain and in the brainstem.
What is the central nervous system?
The central nervous system consists of the brain and spinal cord.
What is the hypothalamus?
The hypothalamus regulates and controls the autonomic nervous system, temperature, appetite, water balance, sleep, and blood vessel constriction and dilation.
What is the nervous system?
The nervous system is a complex, highly organized system that coordinates all the activities of the body.
What is the somatic nervous system?
The somatic nervous system carries messages between the CNS and the body.
What is the cerebellum?
The cerebellum is the section below the back of the cerebrum.
What is the medulla oblongata?
The medulla oblongata is the lowest part of the brainstem.
What are neurons?
Neurons are nerve cells.
What is the sympathetic nervous system?
The sympathetic nervous system works with the parasympathetic in homeostasis, and in times of emergency, prepares the body to act by increasing heart rate, respiration, and blood pressure, and by slowing activity in the digestive tract. aka fight or flight
What is cerebrospinal fluid?
Cerebrospinal fluid is a clear, colorless fluid that fills the ventricles.
What are meninges?
Meninges are the three membranes that cover and protect the brain and spinal cord, (outer to inner) dura mater, arachnoid membrane, pia mater.
What is the parasympathetic nervous system?
The parasympathetic slows heart rate, decreases respiration, lowers blood pressure, and increases activity in the digestive tract after an emergency.
What is the thalamus?
The thalamus acts as a relay center and directs sensory impulses to the cerebrum, and allows conscious recognition of pain and temperature.
