nervous system
sends signals to body.
| Question | Answer |
|---|---|
| nervous system | sends signals to the rest of the body. |
| central nervous system | make up brain and spinal cord. |
| peripheral nervous system | network of nerves connecting to the brain |
| brain | command center of the body, and complex organ. |
| gyrus | ridge or fold on surface of the brain. |
| sulcus | a groove or furor surface of the brain. |
| cerebrum | It is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body. |
| frontal lobe | the largest lobe of the brain, located at the front of the head, and is responsible for higher-level cognitive functions like thinking, planning, and judgment, as well as voluntary movement, personality, and social behavior. |
| parietal lobe | one of the four main lobes of the cerebral cortex, located at the top and back of the skull, behind the frontal lobe. Its primary functions are processing sensory information like touch, temperature, pain, and pressure, |
| temporal lobe | part of brain on sides of brain and controls emotion. |
| occipital lobe | process visual information. |
| cerebellum | it intergrates sensory movement. |
| brain stem | breathing, heart rate and blood pressure. |
| pons | the part of the brainstem that links the medulla oblongata and the thalamus. |
| medulla oblongata | controls involuntary functions. |
| spinal cord | relay motor commands to the brain. |
| nerves | enables sensation and movement. |
| sensory neuron | nerve cells that are activated by sensory input from the environment |
| motor neuron | a nerve cell that transmits signals from the brain and spinal cord to muscles and glands, controlling voluntary and involuntary movements |
| traumatic brain injury | an injury to the brain caused by a bump, blow, or jolt to the head and can range from mild (concussion) to severe. Causes include falls, car accidents, and sports injuries |
| chronic traumatic Encephalopathy | a progressive brain disease linked to repeated head trauma, which can result in cognitive, mood, and behavioral changes, including memory loss, confusion, aggression, and depression |
| concussion | a mild traumatic brain injury caused by a blow or jolt to the head that shakes the brain, leading to symptoms like headache, dizziness, confusion, and memory problems |
| neurological exam | medical evaluation that checks the function of the nervous system, including the brain, spinal cord, nerves, and muscles, through tests of mental status, cranial nerves, motor and sensory function, coordination, and reflexes |
