Brain
| Term | Definition |
|---|---|
| Cerebrum | The cerebrum is the largest part of the brain and is responsible for thinking, memory, emotions, sensory processing, and voluntary movement. |
| Cerebellum | The cerebellum is the part of the brain that controls balance, coordination, posture, and fine motor movements. |
| Brain stem | The brain stem controls basic life functions such as breathing, heart rate, blood pressure, and connects the brain to the spinal cord. |
| Pons | The pons is part of the brain stem that helps regulate breathing, sleep, and relays messages between different parts of the brain. |
| Medulla oblongata | The medulla oblongata controls vital involuntary functions such as breathing, heart rate, blood pressure, and reflexes like swallowing and coughing. |
| Parietal lobe | The parietal lobe processes sensory information such as touch, temperature, pain, and helps with spatial awareness. |
| Occipital lobe | The occipital lobe is responsible for processing visual information, including sight and color recognition. |
| Frontal lobe | The frontal lobe controls decision-making, problem-solving, emotions, speech, and voluntary movement. |
| Temporal lobe | The temporal lobe is responsible for hearing, language comprehension, memory, and emotion. |
| Motor cortex | The motor cortex controls voluntary muscle movements of the body. |
| Sensory cortex | The sensory cortex receives and processes information about touch, temperature, pain, and body position. |
| Corpus callosum | The corpus callosum is a bundle of nerve fibers that connects the left and right hemispheres of the brain, allowing them to communicate. |
| Pituitary gland | The pituitary gland is the “master gland” that releases hormones controlling growth, metabolism, and other endocrine glands. |
| Thalamus | The thalamus acts as a relay station that directs sensory information to the appropriate parts of the brain. |
| Hypothalamus | The hypothalamus maintains homeostasis by regulating body temperature, hunger, thirst, hormones, and linking the nervous system to the endocrine system. |
| Hippocampus | The hippocampus is involved in forming and storing memories and plays a key role in learning and spatial navigation. |
