To which portion of the diencephalon is the pituitary gland attached?
- Thalamus
- Epithalamus
- Hypothalamus (correct)
- Metathalamus
If diffusion across the arachnoid granulations decreases, what is the most likely effect on cerebrospinal fluid (CSF) volume?
If diffusion across the arachnoid granulations decreases, what is the most likely effect on cerebrospinal fluid (CSF) volume?
- CSF volume in the ventricles would decrease.
- CSF flow would reverse into the brain tissue.
- CSF volume in the ventricles would increase. (correct)
- There would be no significant change in CSF volume.

Damage to the primary motor cortex would most likely result in difficulties with which function?
- Regulating heart rhythms
- Understanding language
- Initiating voluntary movements (correct)
- Processing sensory information

Flashcards
What part of the diencephalon is the pituitary gland attached to?
What part of the diencephalon is the pituitary gland attached to?
The pituitary gland, which connects the nervous and endocrine systems, is attached to the hypothalamus.

Where is the primary motor cortex located and what is its function?
Damage to the primary motor cortex, located in the frontal lobe, can impair voluntary movement.

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.
