What does a motor neuron attach to? Motor neurons: Motor neuron are an important type of nerve cell from the nervous system. Motor neurons are effector neurons located in the brain, brainstem, and spinal cord. Motor neurons release a neurotransmitter called acetylcholine which is responsible for ...
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? What type of tissue is res...
Information traveling through a neuron can be bothelectrical and chemical. Electrical impulses calledaction potentialstravel down to the axon terminal and trigger these tiny packages calledvesiclesto open. These vesicles containneurotransmittersthat are released into the synapse to communicate with the next ...
Those ganglia can be found both inhead and neck(and they are part of the cranial nerves) and in the trunk, close to the thoracic and abdominal/pelvic organs. Their preganglionic neurons are located in the cranial nuclei of the brainstem, and in the lateral horn of the sacral spin...
The patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord. What is the purpose of the patellar reflex? The primary purpose of the patellar reflex, which is the stretch reflex of the quadriceps femoris ...
Question: What is an autonomic tone? Autonomic Nervous System: The autonomic nervous system involves all the structures, nerves, and organs that maintain the body's operation without conscious thought required. This is why humans do not suddenly stop breathing and have their hearts stop while they...
gracile tract, and is the site of the axon fibers for the chest, neck, and upper limbs. Above the gracile and cuneate nuclei in the lower closed portion of the medulla is where the medial lemniscus begins, although it does not fully form until the open medulla farther up the brainstem....
Brainstem and spinal cord:Involves feelings of pain and the urge to vomit Neocortex:Incorporates sensory information and involves higher cognitive functions Hippocampus:Involves memory and learning Cerebellum:Involves motor control and coordination THC attaches to cannabinoid receptors and creates a “high”...
Path integration is a powerful navigational mechanism whereby individuals continuously update their distance and angular vector of movement to calculate their position in relation to their departure location, allowing them to return along the most direct
What parts of the brain make up the hind brain? What is the protrusion of the meninges and spinal cord? The brain has many components. For example, what does the brainstem consist of? What part of the brain holds the cell bodies of the neuron? What is the cent...
