|---|---|
| Central Nervous System | The part of the nervous system made up of the brain and spinal cord; it processes information and coordinates responses. |
| Brain | The control center of the body that interprets sensory input, regulates bodily functions, and enables thought, memory, emotion, and movement. |
| Spinal Cord | A long bundle of nerve tissue that connects the brain to the rest of the body and carries messages to and from the brain. |
| Peripheral Nervous System | All nerves outside the brain and spinal cord; it connects the CNS to muscles, organs, and sensory receptors. |
| Brachial plexus | A network of nerves that originate from the spinal cord and supply the shoulder, arm, and hand. |
| Ulnar nerve | A nerve that controls movement and sensation in the ring and little fingers and part of the hand. |
| Radial nerve | A nerve that controls movement and sensation in the back of the arm, forearm, and hand, especially extension movements. |
| Median nerve | A nerve that controls sensation and movement in the thumb, index, and middle fingers; important for fine motor skills. |
| Sciatic nerve | The largest nerve in the body; runs from the lower back through the legs and controls leg movement and sensation. |
| Occipital Lobe | Processes visual information such as color, light, and movement. |
| Cerebellum | Coordinates balance, posture, and smooth muscle movements. |
| Brain Stem | Connects the brain to the spinal cord; controls basic life functions like breathing and heart rate. |
| Frontal Lobe | Responsible for decision-making, personality, voluntary movement, and speech production. |
| Temporal Lobe | Processes hearing, language, and memory. |
| Parietal Lobe | Processes sensory information such as touch, temperature, and pain. |
| Wernicke’s Area | Responsible for understanding spoken and written language. |
| Broca’s Area | Responsible for speech production and language expression. |
| Sensory Cortex | Receives and processes sensory information from the body. |
| Motor Cortex | Controls voluntary muscle movements. |
| Spinal Cord | Raised folds of the brain that increase surface area for processing. |
| Gyrus/Gyri | Grooves or valleys between gyri. |
| Sulcus/Sulci | Structures beneath the brain’s surface involved in emotion, memory, and regulation. |
| Brain Stem | Processes emotions, especially fear and aggression. |
| Amygdala | Maintains homeostasis; regulates hunger, thirst, body temperature, and hormones. |
| Hypothalamus | Process the sense of smell. |
| Olfactory Bulbs | A group of structures involved in emotion, motivation, and memory. |
| Limbic System | Essential for forming new memories and learning. |
| Hippocampus | A thick band of nerve fibers that connects the left and right hemispheres of the brain. |
| Corpus Callosum | Produces melatonin and regulates sleep cycles. |
| Pineal Gland | The master gland that controls hormone release in the endocrine system. |
| Pituitary Gland | Acts as a relay station for sensory information going to the cerebral cortex. |
| Thalamus | Part of the brain stem; helps regulate sleep, breathing, and communication between brain regions. |
