Study Notes
Major Functions of Brain Regions
- Cerebrum: Responsible for higher-level cognitive functions like thought, memory, and voluntary movement.
- Cerebellum: Coordinates movement, balance, and posture.
- Brainstem (Midbrain, Pons, Medulla Oblongata): Controls basic life functions like breathing, heart rate, and swallowing.
- Thalamus: Acts as a relay station for sensory information, except for smell.
- Hypothalamus: Regulates homeostasis, including body temperature, hunger, thirst, and sleep-wake cycles.
- Pituitary Gland: Links the nervous and endocrine systems, releasing hormones.
Pituitary Gland Attachment
- Attached to the hypothalamus.
Arachnoid Granulations and CSF Volume
- Decreased diffusion across arachnoid granulations would increase cerebrospinal fluid (CSF) volume in the ventricles.
Primary Motor Cortex Location
- Located in the frontal lobe of the cerebrum.
Temporal Lobe Damage Effects
- Damage to the temporal lobes affects auditory processing, language comprehension (Wernicke's area), and memory (especially long-term).
Thalamus Sensory Relay
- The thalamus does not relay olfactory (smell) information.
Diencephalon and Body Temperature
- The hypothalamus regulates body temperature.
Medulla Oblongata Damage
- Damage to the medulla oblongata is critical because it controls vital involuntary functions like breathing and heart rate; damage in the cerebrum may not be life-threatening.
