Cerebrum
what does the frontal lobe control
naming things, memory, logic, analyzing, telling time, movement
the central nervous system (CNS) contains...
brain and spinal cord
Alzheimers disease
limbic system
controls emotions, in the center of the brain
what is the insulating layer around neurons that allows nerve impulses to be transmitted quickly and efficiently
the myelin sheath
what does the partial lobe control
conscious perception of the body, sensory
the peripheral nervous system (ANS) contains...
somatic, autonomic, sympathetic and parasympathetic
epilepsy
seizure disorder, discharge from neurons, uncontrolled electrical activity, hallucinations. all four lobes affected
hippocampus (my favorite)
nostalgia. stores memory's related to emotions
what is the space between two neurons that are also impulses that travel from one to another
synapse
what does the occipital lobe control
visuals
difference between somatic and autonomic nervous system
somatic controls voluntary movements
autonomic regulates involuntary bodily functions
parkinsons disease
movements disorder, decrease in dopamine, pill rolling, tremors. effects brain stem and basal ganglia
hypothalamus
regulates appetite, weight, temp, and drives
layers on meninges in order
dura mater, arachnoid, pia
what does the temporal lobe control
speech, smell, hearing, interpreting facial expressions
difference between sympathetic and parasympathetic
sympathetic is fight or flight
parasympathetic brings all bodily symptoms back to normal
meningitis
inflammation of the meninges, the lining that covers and protects the brain and spinal cord. effects only the layers
amygdala
processes fear and aggression
Portion of the brain consisting of the hypothalamus, thalamus, and epithalamus
Diencephalon
difference between Broca's and wernikers area
Brocas is in the frontal lobe and helps to form sentences
wernikers area is in the temporal lobe and helps understand sentences
spinal nerves in order
cervical, thoracic (stability, rotation, bending), lumbar, spinal nerves (afferent and efferent)
encephalitis
inflammation of the brain. effects the temporal and frontal lobes, limbic system and brain stem
brain stem
controls flow of messages between brain and body, controls basic body functions. important for autonomic functions
3 parts
midbrain: visual and auditory (region affected by parkinsons disease)
pons: relay sensory info taste, saliva, highly active during dreaming
medulla oblongata: controls respiration, BP, reflexes
part of the brain that starts puberty
the hypothalamus releases a hormone (GnRH) which travels to the pituitary gland
