brain
| Term | Definition |
|---|---|
| Cerebrum | The largest part of the brain; responsible for thinking, memory, emotions, senses, and voluntary movement. |
| Cerebellum | Controls balance, coordination, posture, and fine motor movements. |
| Brain stem | Connects the brain to the spinal cord; controls basic life functions like breathing and heart rate. |
| Pons | Part of the brain stem that helps regulate breathing, sleep, and relays messages between brain parts. |
| Medulla oblongata | Lowest part of the brain stem; controls vital involuntary actions like heartbeat, breathing, and blood pressure. |
| Parietal lobe | Processes sensory information such as touch, temperature, pain, and spatial awareness. |
| Occipital lobe | Responsible for vision and visual processing. |
| Frontal lobe | Involved in decision-making, personality, emotions, speech, and voluntary movement. |
| Temporal lobe | Processes hearing, language, memory, and emotions. |
| Motor cortex | Area of the frontal lobe that controls voluntary muscle movements. |
| Sensory cortex | Area of the parietal lobe that receives and interprets sensory information from the body. |
| Corpus callosum | A thick band of nerve fibers that connects the left and right hemispheres of the brain. |
| Pituitary gland | The “master gland” of the endocrine system; releases hormones that control growth and other glands. |
| Thalamus | Acts as a relay station, sending sensory signals to the correct parts of the brain. |
| Hypothalamus | Maintains homeostasis by regulating temperature, hunger, thirst, hormones, and emotions. |
| Hippocampus | Plays a key role in learning and forming new memories. |
| Corpus Callosum | A thick band of nerve fibers that connects the left and right sides of the brain, allowing them to communicate. |
| Pineal Gland | A small gland in the brain that produces melatonin, which helps regulate sleep-wake cycles. |
| Pituitary Gland | Often called the “master gland,” it controls other glands and regulates growth, metabolism, and hormones. |
| Thalamus | Acts like a relay station, sending sensory information (like sight, sound, touch) to the right part of the brain. |
| Pons | Part of the brainstem that helps control breathing, communication between brain parts, and movement. |
| Medulla Oblongata | The lowest part of the brainstem that controls automatic functions like heart rate, breathing, and blood pressure. |
| Midbrain | Part of the brainstem that helps with vision, hearing, motor control, and alertness. |
