Study Notes
Brain Structures in Sheep Dissection
-
Superior Colliculus
- Located in the midbrain, involved in visual processing.
- Plays a crucial role in orienting head and eye movements towards stimuli.
-
Pineal Gland
- A small, pinecone-shaped gland in the epithalamus.
- Produces melatonin, regulating sleep-wake cycles and seasonal biological rhythms.
-
Cerebrum
- Largest part of the brain, divided into hemispheres.
- Responsible for higher brain functions including sensory perception, thought, and voluntary movement.
-
Thalamus
- Acts as the brain's sensory relay station, processing and transmitting information.
- Located above the brainstem, it routes sensory and motor signals to the cerebral cortex.
-
Hypothalamus
- Small but crucial, located below the thalamus.
- Regulates autonomic functions, hormone release, and homeostasis (temperature, hunger, thirst).
-
Cerebral Peduncle
- Bundles of nerve fibers located in the midbrain, connecting the cerebrum and lower brain structures.
- Involved in motor control and coordination.
-
Pons
- A major structure in the brainstem, located above the medulla.
- Functions as a bridge between different parts of the nervous system and plays a role in regulating breathing and sleep.
-
Medulla Oblongata
- The lowest part of the brainstem, connecting the brain to the spinal cord.
- Controls vital autonomic functions like heart rate, blood pressure, and respiration.
