Brain Parts (functions, subparts) Flashcards
Medulla Oblangata
Reflexive, involuntary control of heart, breathing & blood vessels
Pons
Timing of subconscious breathing
Midbrain (corpora quadrigemina)
- Superior colliculi: Filter and relay visual stimuli
- Inferior colliculi: Filter and relay auditory stimuli
- Reflexive control of eye movement, focusing lens, and pupil diameter
Hypothalamus (Mammilary body)
Control of automatic nervous system (ANS) and pituitary gland; regulates involuntary body functions, homeostasis
Thalamus (Interthalamic adhesion/mass)
- Perception of sensation and emotions
- Relay afferent/efferent impulses to/from the cerebrum
Pineal gland
Endocrine gland; secretes melatonin
Pituitary gland (Infundibulum)
Endocrine gland; secretes many hormones
(cerebrum) Cerebral cortex, cerebral tracts, white matter vs. grey matter, fornix
Will (choice), intelligence, memory, awareness, personality
(cerebrum) Longitudinal fissure
Divides cerebrum into cerebral hemispheres.
Left Cerebral Hemisphere
Dominates speech sounds and in understanding sequential, rational, and analytical concepts
Right Cerebral Hemisphere
Dominates in non-speech sounds, spatial perception, holistic, emotional, and artistic concepts
Frontal Lobe
Voluntary control over muscles, learning, planning, and higher physiological functions.
Parietal Lobe
Perception of sensations of touch, temperature, taste, and body position.
Temporal Lobe
Perception of auditory sensations and related speech center
Occipital Lobe
Perception of visual sensations
