Parts of the Brain
Cerebrum
- voluntary
Cerebral cortex: outer layer of the cerebrum
1. Frontal lobe
- Includes motor cortex
- Moving, dancing, walking
- Eye movements
- Speech production
- Thinking, planning, problem solving, decision making
- Emotions
2. Parietal lobe
- Includes somatosensory cortex
- Awareness of sensation
- Touch, pressure, pain
- Reacting to environment
3. Occipital lobe
- Visual cortex
- Vision
4. Temporal lobe
- Auditory cortex
- Hearing
- Olfactory
- Language
- Memory
Cerebellum
- Balance
- Coordination
- Posture
Brainstem
1. Midbrain
- Reflexes
- Visual
- Auditory
2. Pons
- “Bridge”
- Relays information between cerebrum and cerebellum
3. Medulla oblongata
- Involuntary
- Blood pressure, heart rate, oxygen levels, digestion, reflexes
Thalamus
- “Router”
- Relays sensory signals to the cerebral cortex
Hypothalamus
- Maintains homeostasis
- Links nervous system to endocrine system
- Temperature
- Hunger and thirst
- Circadian rhythm (sleep wake cycles)
- Controls the endocrine system (big boss)
Pituitary gland
- Makes hormones: ADH, FSH, GH, oxytocin
- “Assistant manager” of endocrine system
Pineal
- Melatonin
