| Brain Stem | Connects the brain to the spinal cord; controls automatic life functions like breathing and heart rate. |
| Pons | Part of the brain stem; helps regulate breathing and is involved in sleep and relaying messages. |
| Medulla Oblongata | Controls vital involuntary functions like breathing, heart rate, and blood pressure. |
| Parietal Lobe | Processes touch, temperature, pain, and helps with spatial awareness. |
| Occipital Lobe | vision |
| Frontal Lobe | Controls decision-making, planning, personality, movement, and problem-solving. |
| Temporal Lobe | Handles hearing, language, and memory. |
| Motor Cortex | controls voluntary muscle movements |
| Sensory Cortex (Somatosensory Cortex) | Processes information about touch, pressure, pain, and temperature. |
| Corpus Callosum | A large bundle of nerve fibers that connects the left and right hemispheres of the brain. |
| Pituitary Gland | The "master gland"; releases hormones that control growth, metabolism, and other glands in the body. |
| Thalamus | The brain's relay station; sends sensory information (except smell) to the correct brain areas. |
| Hippocampus | Important for forming new memories and learning. |
| Central Nervous System (CNS) | The main control system of the body; made up of the brain and spinal cord. |
| Brain | The organ that controls thoughts, memory, emotions, movement, and body functions. |
| Spinal Cord | A long bundle of nerves that sends messages between the brain and the rest of the body. |

| Brachial Plexus | A network of nerves that controls the shoulder, arm, and hand. |
| Ulnar Nerve | A nerve that runs down the arm to the hand; controls the pinky and ring finger. |
| Radial Nerve | A nerve that controls movement and feeling in the back of the arm and hand. |
| Median Nerve | A nerve that controls the thumb, index, and middle fingers; important for hand movement. |
| Sciatic Nerve | The largest nerve in the body; runs from the lower back down the legs. |
| Wernicke’s Area | Responsible for understanding spoken and written language. |
| Broca’s Area | Responsible for producing speech and forming words. |
| Gyrus / Gyri | Raised folds on the surface of the brain. |
| Sulcus / Sulci | Grooves or indentations between gyri. |
| amygdala | anger and fear, fight or flight |
| hypothalmus | temperature, hunger, thirst, hormones |
| Olfactory Bulbs | Process smell information. |
| Limbic System | A group of structures involved in emotion, motivation, and memory. |
| corpus callosum | Connects the left and right hemispheres of the brain. |
| Pineal Gland | Releases melatonin; controls sleep-wake cycles. |
| mid brain | Controls reflexes related to vision and hearing. |
