1. The part of the nervous system responsible for transporting information throughout the body is A. the neuron. The neuron is a specialized cell that can transmit electrical signals, called action potentials, to relay information between different parts of the body.
To understand this, you can consider how the neuron functions. It consists of three main parts: the cell body, dendrites, and axon. The dendrites receive signals from other neurons or sensory receptors. These signals are then transmitted to the cell body, which integrates and processes the information. Finally, the processed information is sent along the axon, a long fiber-like extension of the neuron, to other neurons or to muscles and glands, enabling communication and coordination within the body.
2. The brain and spinal cord make up the C. central nervous system. The central nervous system (CNS) is responsible for processing and coordinating information throughout the body. It consists of the brain and the spinal cord, both of which play crucial roles in regulating bodily functions and controlling behavior.
To understand this, imagine the CNS as the control center of the body. The brain is located within the skull and is responsible for higher cognitive functions, such as perception, memory, and decision making. It also controls voluntary movements and regulates various autonomic functions. The spinal cord, on the other hand, is a long, cylindrical structure that extends from the base of the brain down the back. It acts as a communication pathway between the brain and the rest of the body, allowing information to be transmitted to and from different parts of the body.
3. Uncontrolled muscle spasms due to a flood of brain activity are called D. a seizure. A seizure occurs when there is abnormal electrical activity in the brain, leading to temporary disruptions in normal brain function. This can result in various symptoms, such as muscle convulsions, loss of consciousness, and sensory disturbances.
To understand this, it is important to know that the brain communicates through electrical signals generated by neurons. During a seizure, there is abnormal synchronization or excessive electrical discharges in a large number of neurons, disrupting the normal functioning of the brain. The symptoms experienced during a seizure can vary depending on the area of the brain affected and the severity of the seizure.
4. The victim of a vehicle accident who cannot feel his or her legs is likely experiencing A. spinal trauma. Spinal trauma refers to injuries that occur to the spinal cord, typically resulting from accidents or significant trauma to the spine. These injuries can lead to partial or complete loss of motor and sensory function below the level of the injury.
To understand this, you should know that the spinal cord is a bundle of nerves that runs through the vertebral column (spine). It carries signals between the brain and the rest of the body, allowing for movement and sensation. When the spinal cord is injured, the communication between the brain and the affected body parts may be disrupted. In the case of a vehicle accident, the impact or trauma can cause damage to the spinal cord, leading to paralysis or loss of sensation in the legs.
5. Alcohol is categorized as A. a drug and C. a depressant. Alcohol is a substance that affects the central nervous system, and it can have various effects on the body and mind.
To understand this, it is important to know that drugs are substances that alter the normal functioning of the body, either beneficially or harmfully. Alcohol falls into this category as it has a significant impact on the nervous system. Specifically, alcohol acts as a depressant, meaning it slows down or depresses the activity of the central nervous system. This can result in symptoms such as decreased coordination, impaired judgment, and reduced reaction times.
