NeuroAnotomy Flashcards
Brain protected by?
DAP (Dura, arachnoid, pia matter)
Interneurons
reflexes
Somatic Nervous System
Voluntary Control
Autonomic Nervous System
Automatic, involuntary
Parasympathetic
Conserve Energy (Rest and Digest)
Parasympathetic responses?
peristalsis (moving food), lower HR, pupils constrict, bladder contraction, digestion, bile released (produced in liver, released by gall bladder) acetylcholine
Sympathetic
Stress (Fight of flight)
Sympathetic responses?
Increased HR, dilation of pupils, relax bronchi, inhibit peristalsis, adrenaline production
hindbrain
vital functions
hindbrain
balance, motor coordination
forebrain
logic, complex processes
Pons
Relays info and regulates sleep
Medulla Oblongata
Breathing, Vitals, survival
cerebellum
balance, posture
Superior Colliculus
Vision
Inferior Colliculus
Audio
Thalamus
Sensory Processing station (except smell)
hypothalamus
makes hormones, endocrine system, homeostasis
Oxytocin
Milk production
Lateral Hypothalamus? Damage?
Controls hunger (never get hungry if damaged)
Ventromedial Hypothalamus? Damage?
Full center (never get hungry if damaged)
Interior Hypothalamus? Damage?
Libido (no sex drive if damaged)
Posterior pituitary
releases hormones
pineal gland
produces melatonin (sleep)
Basal Ganglia
Smooth movements (parkinson’s if damaged)
septal nuclei
pleasure center (addiction)
Amygdala
emotion (fear and rage)
Hippocampus
memory and learning (if you see a hippo on campus, you will never forget it)
Parietal Lobe
Integrates sensory info
Occipital Lobe
Vision
Temporal Lobe
Audio, Memory, Emotion, Language
Wernicke’s Area
Speech Production (context)
Broca’s Area
Speech (actually doing it)
Frontal Lobe
Inhibition, executive function
Associated Area
Has lots of things coming together
Projection Area
Working Solo
Motor Cortex
Voluntary movement
Somatosensory cortex
sensory center
acetylcholine
parasympathetic nervous system (in CNS or PNS)
Attention and arousal
Epinephrine/ norepinephrine
PNS (sympathetic response)(wakefulness and alertness)
Dopamine
CNS (movement and posture)
Serotonin
CNS (mood) (both manic and depressive states)
GABA
CNS (brain stabilizer)
Endorphins
CNS Painkillers
Pinpoint pupils
suggest opiates
