impulses
section located below the cerebrum and at the top of the brainstem. Conducts impulses between brain parts and certain eye and auditory reflexes
Midbrain
mass of nerve tissue well protected by membranes or the cranium, or skull
Brain
contains the sympathetic and parasympathetic nervous systems, which work together to control involuntary body functions
Autonomic nervous system
hollow space that connect with each other and with the space under the arachnoid membrane
Ventricles
regulates heartbeat, respiration, swallowing, coughing and blood pressure
Medulla oblongata
conducts messages to other parts of the brain for chewing, tasting, and saliva production
Pons
section below the back of the cerebrum
Cerebellum
basic structural unit of the nervous system
Neuron
continues down from the Medulla oblongata and end at the first or second lumbar vertebrae
Spinal cord
works together with the sympathetic system to maintain homeostasis
Parasympathetic
carries messages between the CNS and body
Somatic nervous system
largest and highest section of the brain
Cerebrum
complex, highly organized system that coordinates all the activities in the body
Nervous system
regulates and controls the autonomic nervous system, temperature, appetite, water balance, sleep and blood vessel constriction and dilation
Hypothalamus
6 oz to ml
177
acts as a relay center and directs sensory impulses to the cerebrum
Thalamus
section located between cerebrum and midbrain
Diencephalon
combination of many nerve fibers located outside the brain and spinal cord
Nerves
(CNS) consists of the brain and spinal cord
Central nervous system
8 oz to ml
236
works together with the parasympathetic system to maintain homeostasis
Sympathetic
three membranes that cover and protect the brain and spinal cord
Meninges
(PNS) consists of the nerves and has 2 divisions; (SNS) and (ANS)
Peripheral nervous system
fills the ventricles, clear colorless fluid
Cerebrospinal fluid
2 oz to ml
