Study Notes
Brain Basics
- The brain is part of the central nervous system.
- The brain controls many bodily functions.
- The average human brain weighs about 3 pounds.
- The brain can be divided into two hemispheres.
- Each cerebral hemisphere is divided into four lobes (frontal, parietal, temporal, and occipital)
- Sulci are grooves in the brain.
- Gyri are folds in the brain.
- The folding of the brain increases its surface area.
Regions of the Brain
| Regions | Location | Function |
|---|---|---|
| Cerebrum | Largest part of the brain | Higher-level functions, like thinking, learning, and memory |
| Cerebellum | Located at the back of the brain | Coordination of movement, posture, and balance |
| Cerebral Cortex | Outer layer of the cerebrum | Higher-level thinking and processing, sensory perception |
| Corpus Callosum | Bundle of nerve fibers connecting the hemispheres | Communication between the two hemispheres |
| Pons | Structure connecting the cerebrum w/ other parts | Relays signals between various parts of the brain |
| Medulla Oblongata | Lower part of the brainstem | Control of involuntary functions like breathing, heart rate, and digestion |
| Thalamus | Located in the center of the brain | Relay station for sensory information |
| Hypothalamus | Located below the thalamus | Regulates hormones, body temperature, and other body processes |
| Pituitary Gland | Located beneath the hypothalamus | Produces hormones that regulate various bodily functions |
| Brain Stem | Composed of the midbrain, pons, and medulla | Control of basic body functions, regulates consciousness |
Spinal Cord Basics
- The spinal cord is part of the central nervous system.
- Spinal nerves are attached to the spinal cord.
- The spinal nerves are divided into different sections.
- There are many pairs of spinal nerves leaving the spinal cord.
- Dorsal roots carry sensory information.
- Ventral roots carry motor information.
- The spinal cord is protected by bony structures.
CNS Injuries
- Brain and spinal cord injuries can have significant effects.
- The brain is protected by protective layers in the skull.
- Damage to the brain stem can cause life-threatening issues.
- Different protective measures protect the delicate brain.
