Nervous system
| Question | Answer |
|---|---|
| Nervous System | The body’s command center responsible for coordinating all actions, thoughts, and functions by sending an electrical signal between the brain and spinal cord. |
| Central Nervous System (CNS) | The CNS process thoughts, emotions, and memories, and sends signals throughout the body to control movement and sensations. |
| Peripheral Nervous System (PNS) | The part of the nervous system that includes all nerves outside of the brain and spinal cord. |
| Brain | An organ of soft nervous tissue contained in he skull of vertebrates functioning as the coordinating center of sensation and intellectual and nervous ability. |
| Gyrus | A ridge on the surface of the cerebral cortex of the brain, the folds which are separated by grooves increase the brain’s surface area which allows for more neurons and greater cognitive abilities. (Plural Gyri) |
| Sulcus | A groove on the surface of the brain that separates adjacent folds or ridges called “Gyrus”. |
| Cerebrum | The largest part of the brain, which is responsible for conscious thoughts, memory, and coordination movement. |
| Frontal Lobe | The lobe located right behind your forehead that is used for a lot of high level cognitive functions such as motor functions (Voluntary) and decision making. |
| Parietal Lobe | The part of the brain that is located at the top back of the head which process senses such as touch, taste, pain, and temperature. |
| Temporal Lobe | This lobe is located in the brain behind the temples and it is most commonly associated with processing auditory information, Language comprehension etc. |
| Occipital Lobe | This lobe is located at the back of the skull and is primarily responsible for processing visual information. |
| Cerebellum | A part of your brain in the back of the head between the cerebrum and brain stem, which controls balance (walking) , and other complex motor functions. |
| Brain Stem | The part of the brain that is connected to the spinal cord, it controls vital functions such as breathing, heart rate, and blood pressure. |
| Pons | Part of the CNS system, located at the base of the brain, between the medulla oblongata and the midbrain (part of the brainstem). |
| Medulla Oblongata | The lowest part of the brain, connecting to the spinal cord and it is crucial for controlling involuntary functions like breathing, heart rate, and swallowing. |
| Spinal Cord | A column of nerve tissue that runs from the base of the skull down to the center of the back. it is covered by three thin layers of protective tissue. (CNS) |
| Nerves | A bundle of fibers that receives and sends messages between the body and brain, the messages are electrical. |
| Sensory Neuron | Nerve cells that are activated by sensory input from the environment. |
| Motor Neuron | Part of the CNS system and connect to muscles, glands, and organs, these neurons transmit impulses from the spinal cord to other muscles. |
| Traumatic Brain Injury (TBI) | An injury to the brain caused by an external force like a bump/jolt to the head. |
| Chronic Traumatic Encephalopathy (CTE) | A progressive and degenerative brain disease linked to receptive head trauma. |
| Concussion | A mostly mild traumatic brain injury caused by a bump, blow, or jolt to the head. |
| Neurological exam | A doctors evaluation of an individual’s nervous system. |
