- What is the controlling and communicating system of the body, which sends electrical signals?
- Nervous system
- What moniters changes in and out of the body?
- Sensory input
- What processes information, and determines the apporpriate response?
- Integration
- What responds to change/ info from the sensory division?
- Motor Output
- What is the integration command center of the body?
- CNS
- What is the thing that goes between the CNS and the rest of the body?
- PNS
- What are the two divisions of the PNS?
- Motor, sensory
- What is the efferent?
- Motor division
- What is the afferent?
- sensory division
- What are the two divisions of the motor division?
- Somatic NS, autonomic NS
- What is the part of the NS that controls voluntary mvmt/control (skeletal musc)?
- Somatic NS
- What is the part of the NS that is in control of involuntary mvmt/control (visceral motor sys)?
- Autonomic NS
- What are the two divisions of the Autonomic NS?
- Sympathetic, Parasympathetic
- Sympathetic or parasympathetic: What controls the "fight or flight" reaction?
- sympathetic
- Sympathetic or parasympathetic: What is stress induced?
- Sympathetic
- Sympathetic or parasympathetic: What is associated with excitement, exercise, emergency and embarrassment?
- Sympathetic
- Sympathetic or parasympathetic: what is associated with "resting and digesting"?
- parasympathetic
- Sympathetic or parasympathetic: What is rest-induced?
- parasympathetic
- Sympathetic or parasympathetic: What is associated with digestion, diuresis?
- parasympathetic
- What is "nerve glue," which supports, insulates, and protects nerves of CNS?
- Neuroglia
- What makes up half of nerve tissue?
- Neuroglia
- What controls the chem. environment of nerve cells, protects nerves from toxins in blood?
- Astrocytes
- What surrounds neuron cellb odies with ganglia?
- Satellite cells
- What controls the chemical envirentment of the cell?
- Satellite cells
- What processes information from the motor cortex and sensory receptors?
- cerebellum
- What provides precise timing/coordination for smooth movements with skeletal muscle?
- cerebellum
- What is vital for involuntary functions?
- brain stem
- What are the three main parts of the brain stem?
- midbrain, pons, medulla oblongata
- What is the large descending motor tracts to spinal cord?
- cerebral penducle
- What are the fiber tracts connecting the midbrain to the cerebellum?
- cerebral penducle
- What is the part of the midbrain for visual reflex?
- corpora quadrigemina
- What contains the auditory reflex?
- corpora quadrigemina
- What relays information from the cerebrum to the cerebellum?
- Pons
- What is the reflex center for respiratory rhythm?
- Pons
- What is the autonomic center to regulate blood pressure and resp. rhythm, coughing/ sneezing/ vomiting/ hiccupping/ swallowing?
- medulla oblongata
- What is the inter brain called?
- Dienchephalon
- What sits atop the brain stem and is encased by the cerebrum?
- Dienchephalon
- What are the four parts of the dienchephalon?
- Thalamus, hypothalamus, pineal gland, choroids plexus?
- What is the relay station for sensory impulses?
- Thalamus
- What mediates sensation and motor activities and helps process memory?
- thalamus
- What is the autonomic control center?
- hypothalamus

- gyri
- What are the grooves in the cerebral hemispheres?
- fissures
- What are the three kinds of functional areas in the cerebral hemispheres?
- motor (vol. mvmt)sensory (awareness of sensation), association (integration of info)
