Document Summary
Every single synapse adds to delay of response: spinal reflexes. Inferior portion resembles spinal cord and superior has thin memberus covering. Relays sensory info to thalamus and other centers within brainstem. Contains centers that are regulating autonomic functions like hr, bp, digestion: pons: connects the cerebellum to the brainstem. Contain nuclei controlling somatic and visceral functions: mesencephalon (midbrain): nuclei in the mesencephalon process visual and auditory information. Coordinate reflexive somatic motor responses to both visual and auditory stimuli. contains centers to maintain levels of consciousness: diencephalon: attaches the mesencephalon to the cerebrum, subdivisions. Deep within brain (1) epithalamus: contains hormone secreting pineal gland (endocrine structure) (2) thalamus: sensory info relaying and processing center (3) hypothalamus: visceral control center. Narrow stalk that connects hypothalamus to pituitary gland. Centers for emotions, autonomic nervous system function and hormone production. important link between nervous and endocrine: cerebellum: second largest part of the brain. Output of these modifiers activity of lower areas.
