Biology and Behavior Flashcards
Types of Neurons
Motor (Efferent - movement from systems to muscle)
Interneurons
Sensory (Afferent - sense from organ to system)
Two branches of the autonomic system
Parasympathetic (Rest and digest)
Sympathetic (Fight or flight)
Parasympathetic does what to:
Pupils
Saliva Flow
Bronchi
Heartbeat
Piloerection/Sweating
Peristalsis and Secretion
Bile
Glucose Production
Secretion of Adrenaline
Bladder contraction
Orgasms
CONSTRICTS Pupils
STIMULATES Saliva Flow
CONSTRICTS Bronchi
SLOWS Heartbeat
NOTHING Piloerection/Sweating
STIMULATES Peristalsis and Secretion
STIMULATES Bile
NOTHING Glucose Production
NOTHING Secretion of Adrenaline
STIMULATES Bladder contraction
NOTHING Orgasms
Parasympathetic does what to:
Pupils
Saliva Flow
Bronchi
Heartbeat
Piloerection/Sweating
Peristalsis and Secretion
Bile
Glucose Production
Secretion of Adrenaline
Bladder contraction
Orgasms
DILATES Pupils
INHIBITS Saliva Flow
RELAXES Bronchi
ACCELERATES Heartbeat
STIMULATES Piloerection/Sweating
INHIBITS Peristalsis and Secretion
NOTHING Bile
STIMULATES Glucose Production
STIMULATES Secretion of Adrenaline
INHIBITS Bladder contraction
STIMULATES Orgasms
Three Parts of the Brain
HIND (Cerebellum, Medulla Oblongata, Reticular Formation)
MID (Inferior/Superior Colliculi)
FORE (Thalamus, Hypothalamus, Basal Ganglia, Limbic System)
Fore Function
Thalamus - Relay station for sensory info
Hypothalamus - Homeostasis
Basal Ganglia - Maintain posture stability
Limbic System - Emotion and memory
Mid Function
Colliculi:
Inferior - Main sound processing and recognition center
Superior - Neck/eye coordination
Hind Function
Cerebellum - Balance
Medulla Oblongata - Control automnic activities
Reticular Formation - Motor coordination
Cerebral Cortex Lobes
Frontal, Parietal, Occipital, Temporal
Frontal Lobe Function
Executive Function
Impulse Control
Long-term planning (Prefrontal Cortex)
Motor Function (Primary Motor Cortex)
Speech Production (Broca’s Area)
Parietal Lobe Function
Sensation of touch, pain, temperature, pressure (Somatosensory cortex)
Spatial Processing
Orientation/Manipulation
Occipital Lobe Function
Visual Processing
Temporal Lobe Function
Sound Processing (Auditory Cortex)
Speech Perception (Wernicke’s area)
Memory and Emotion (Limbic System)
Neurotransmitter
Acetylcholine
Epi/Nor- ephrine
Dopamine
Serotonin
GABA
Endorphins
Behavior
Voluntary muscle control (Parasym)
Fight or Flight
Posture Stability
Mood, Sleeping, Eating
Brain stability
Natural Painkillers
