1. What is the primary function of the nervous system? 2. Why does the cerebral cortex contain so many folds? 3. What is a nerve impulse? 4. What are Schwann cells and what do they form? 5. What is an all or none response?
A nerve impulse is when the peripheral nerves of the body chemically and electrically send a message to the brain. The impulse then tells the brain to initiate a certain movement or sensation.Answer and Explanation: A nerve impulse is initially caused by a stimulus in the environment. A ...
How does nerve impulse travel in axon ? View Solution A : Transmission of the nerve impulse across a synapse is accomplished by neurotransmitters . R : Transmission across a synapse usually requires neuro transmitters because there is space , i.e., synaptic cleft, that separates one neuron from...

The components of the nervous system involved in the skeletal muscle movement is the motor division. The motor impulse moves through the body by traveling through efferent fibers. A motor unit is a neuron and also that is where all the other muscle fibers are connected. 967 Words 4 Pages Goo...
What is the difference between a lesion and a tumor in the brain? Both lesions and tumors in the brain represent abnormal areas, but they are not the same. A lesion is a broad term that refers to any abnormal tissue or damage in the brain, whereas a tumor, is a specific type of les...
But the aesthetic sphere of the mind, its longings, its pleasures and pains, and its emotions, have been so ignored in all these researches that one is tempted to suppose that if either Dr. Ferrier or Dr. Munk were asked for a theory in brain-terms of the latter mental facts, they ...
The cerebral cortex is a sheet of neural tissuethat is outermost to the cerebrum of the mammalian brain. It has up to six layers of nerve cells. It is covered by the meninges and often referred to as gray matter. Is the insular cortex involved in pain?
Hibernation: This topic refers to research focusing on the physiological processes involved in hibernation. Hormones: This topic includes research focusing on the hormonal control of neural processing and behavior. Impulse control: Most research represented at the ICN on impulse control investigated impulse...
Neurotransmitters are vital to your body’s ability to function. Their role is to carry messages from one nerve cell to another cell, which can be another nerve cell, a muscle cell, or a gland cell. Yournervous systemhouses a wide network of nerves that work to send and receive messages ...
