Brain and Nervous System Flashcards
Spinal Cord (3)
- Information integration and processing
- Simple reflexes
- Primitive processes (sex, walking, peeing)
Medulla (3)
- Relaying information between brain parts
- Autonomic functions
- Respiratory and rhythmicity centers
Pons
Balance/antigravity/posture
Cerebellum (2)
“Little Brain” -
- Complex movements
- Balance/antigravity
Midbrain
- Visual/audio information
2. RAS (reticular activating system)
Thalamus
Sensory information
Hypothalamus (2)
- Emotion
2. Endocrine functions (hormonal regulation, controls pituitary gland)
Telencephalon - Left (3)
- Motor
- R body
- Speech
Telencephalon - Right (3)
- Visual-spatial reasoning
- Music
- L body
Corpus Callosum
Axons connecting cerebral hemispheres
Cerebellum
Wrapping of the cerebral cortex - 4 lobe pairs
Learning/behaviors
Frontal Lobe (4)
- Voluntary movement
- Complex reasoning
- Problem-solving
- Executive functions (planning, organizing)
Parietal Lobe
Sensation - touch, temp, taste
Temporal Lobe (5)
- Hearing
- Smelling
- ST memory
- Language comprehension
- Emotion
Occipital Lobe
Vision
Basal Ganglia
- Voluntary movement
- Procedural learning
- Coordinating movement
Vagus Nerve
Communicates with heart and stomach to regulate HR and GI activity (autonomic)
Adrenal Medulla
Inner adrenal gland - sympathetic NS
Releases adrenaline/epinephrine that stimulates the heart
Adrenal Cortex
Outer adrenal gland Releases 3 things: 1. Glucocorticoids (cortisol) 2. Mineralocorticoids (aldosterone) 3. Sex hormones
Auditory Hair Cell
Detects vibrations from sound waves (cochlea)
Vestibular Hair Cells
Detects position relative to gravity (semicircular canals)
Cochlea
Releases excess pressure
Vestibular Complex
Includes: utricle, saccule, ampullae
Balance
Iris
Regulate diameter of pupil
