| Term | Definition |
|---|---|
| Cerebrum | Definition: The largest part of the brain, made of two hemispheres. Function: Controls thinking, reasoning, emotions, voluntary movement, and senses. |
| Cerebellum | Definition: The “little brain” at the back of the skull. Function: Controls balance, coordination, posture, and fine-tuned movements. |
| Brain Stem | Definition: The lower part of the brain connecting to the spinal cord. Function: Controls basic life functions like breathing, heartbeat, and digestion. |
| Pons | Definition: A part of the brainstem above the medulla. Function: Helps with sleep, breathing, facial expressions, and relaying messages. |
| Medulla Oblongata | Definition: The lowest part of the brainstem. Function: Controls vital automatic functions like breathing, heart rate, blood pressure, and swallowing. |
| Parietal Lobe | Definition: Upper middle part of the brain. Function: Processes touch, temperature, pain, and helps with spatial awareness. |
| Occipital Lobe | Definition: The back of the brain. Function: Responsible for vision and interpreting visual information. |
| Frontal Lobe | Definition: The front portion of the brain. Function: Controls decision-making, problem-solving, planning, personality, and voluntary movement. |
| Temporal Lobe | Definition: The sides of the brain near the ears. Function: Handles hearing, memory, language understanding, and emotions. |
| Motor Cortex | Definition: A strip in the frontal lobe. Function: Controls voluntary muscle movements. |
| Sensory Cortex | Definition: A strip in the parietal lobe. Function: Receives and processes touch and body sensations. |
| Corpus Callosum | Definition: A thick band of nerve fibers connecting both hemispheres. Function: Allows communication between the left and right sides of the brain. |
| Pituitary Gland | Definition: A small hormone gland at the base of the brain. Function: Controls growth, hormones, metabolism, and other glands in the body. |
| Thalamus | Definition: A relay station deep in the brain. Function: Sends sensory information (except smell) to the correct brain areas. |
| Hypothalamus | Definition: A small region below the thalamus. Function: Controls hunger, thirst, temperature, hormones, sleep, and homeostasis. |
| Hippocampus | Definition: A curved structure in the temporal lobe. Function: Forms new memories and helps with learning. |
