Questions On The Common Nerve Supply

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

The part of the peripheral nervous system that carries sensory information to the CNS is designated

a) The structures and the afferent division of the peripheral nervous system that are involved in

Three other organs that belong to the digestive system are the esophagus, pancreas and the small intestine.

Consist of oral cavity, esophagus, gallbladder, liver, stomach, duodenum, pancreas, colon, cecum, appendix, jejunum, and rectum.

The next nerve is responsible for the sensory impulses to different parts of

In the brainstem, the connections between the vestibular nuclei and the parabrachial nucleus are the link between vestibular system

There are 12 Cranial Nerves which all serve a very important purpose within each and every one of our bodies. The twelve cranial nerves are Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Accessory, and last but certain not least Hypoglossal. Each nerve plays a different role for example the Olfactory nerve gives sense to smell, and the Optic nerve gives us sense of vision. The Oculomotor give us the motor skills to adjust the size of our pupils, raise our eyelids, etc. This particular nerve is also parasympathetic to the pupil, which causes accommodation as well as constriction. Another nerve that has to do with our motor skills is the Trochlear nerve, which allows the eye

Esophagus is located through the mouth. You go down the throat and into the stomach. I can remember this by tracing the path in the photo.

In between the esophagus and stomach there is a valve called the LES valve. The

Disorders of cranial nerves may affect the connections between cranial nerve centers within the brain. A disorder may affect one or more nerves at a time, and the presence and

Cranial nerves originate from the brain and provide information from the brain to parts of the body. Cranial nerves provide input to both sides of the body. The 12 cranial nerves are as follows:

The CNS contains the brain and spinal cord. Its main functions include: processing, integrating, and coordinating sensory information and motor instructions. The sensory data conducts information that is being processed from internal and external conditions the body is experiencing. Motor commands regulate and control peripheral organs (skeletal muscles). The brain functions under memory, emotions, learning, and intelligence. The PNS consist of the neural tissue found outside of the CNS. It functions in sending data to the CNS which motor commands are than carried out to the peripheral tissues/systems. Multiple nerve fibers send sensory data and motor commands in the PNS. The nerves that assist with transmitting data include the cranial nerves and spinal nerve. However, the PNS can be divided into afferent (to bring in) and efferent (to bring out) divisions of transferring data. The afferent division functions in bringing in sensory data to the CNS. Sensory structures are receptors that detect internal/external environmental change and adjusting accordingly. The efferent division functions in carrying out motor commands from the CNS to glands, muscles, and adipose tissue. The efferent division contains somatic

There are nerve cells and nerve fibers located in the first layer of the cortical area

Many cranial nerves deal with vision one of these is the optic nerve. The nerve that carries sensory information from the eyes to the brain would be the optic nerve. The cranial nerves that carry motor commands from the brain to the eye would be oculomotor nerve, trochlear nerve and the abducens nerve. The muscles that the
