Exam 4 Flashcards
Brain and spinal cord, and brainstem
Cns
Anything but brain and spinal cord; cranial nerves, ganglia, spinal nerves
Pns
Divisions of the PNS
Somatic and autonomic
Voluntary actions
Somatic
Involuntary actions; controls cardiac, smooth, and some skeletal muscle
Autonomic
Divisions of the autonomic nervouse system
Sympathetic and parasympathetic division
Fight or flight; increased heart rate, faster breathing, relaxed airways; emergency mode
Sympathetic
Rest or digest; slow heart rate, promote digestion; normal/everyday
Parasympathetic
Cerebellum, pons, medulla oblongata
Hindbrain
Cerebrum, cerebral cortex, limbic system
Forebrain
Divisions of limbic system
Hippocampus, amygdala, olfactory bulb
Maintains normal homeostatic processes
Medulla oblongata
Maintains balance and coordinate hand eye movements
Cerebellum
Serves as a relay between cerebellum and other areas of brain; regulates rate and depth of breathing
Pons
Processes sensory inputs of several types, including vision, olfaction, and audition
Midbrain
Thalamus, hypothalamus, and epithalamus
Diencephalon (under forebrain)
Occipital, temporal, parietal, and frontal lobe
Cerebral cortex
Relays sensory information to cerebrum; gets input from all sensory systems except olfaction
Thalamus
Produces hormones regulating pituitary gland, which regulates hormone secretion from other glands
Great importance for homeostasis
Hypothalamus
Production of cerebrospinal fluid, control of food and water intake, and rythmic and seasonal behaviors; pineal gland produces melatonin
Epithalamus
Planning, learning, and fine tuning movements; complex circuitry to initiate or inhibit movements; affected in parkinson disease
Basal nuclei
Cerebrum(telencephalon)
Basal nuclei
Emotions, learning, memory and perception of smells
Limbic
Understand and remember emotional situations, recognize emotional expressions in others
Amygdala
