Nervous System The nervous system is a complex collection of nerves and specialized cells known as neurons. Its function is to transmit signals between different parts of the body, and is the body’s decision and communication center.

Brain Sensory nerves send messages to the brain makes sense of it and sends responses to the rest of the body. The brain is made up of three main parts which all contain multiple sections and lobes.

Brain Stem The brain stem is found under the limbic system. It’s responsible for basic vital life functions. Like breathing, heartbeat, and blood pressure. The brain stem is made up of the midbrain, pons, and medulla.

Ears and Eyes The ear has three parts: the outer ear, the middle ear, and the inner ear. Its function is to transduce variations in air pressure into electrical signals that can be interpreted by the brain. The function of the eye is to work with the brain to provide vision.

Nerves and Olfactory Cells Nerves primary function in the body are communication. They pass electrical and chemical messages to neurons and target cells. Olfactory cells are specialized cells of the nose. Their function is receptors for smell.

Spinal Cord The spinal cord is made up of bundles of nerve fibers. Its functions are to conduct sensory information from the peripheral nervous system to the brain, conduct motor information from the brain to the body, and it serves as a minor reflex center.

Taste Buds Taste buds take place on the tongue. They enable us to distinguish four main tastes, and provide information about what is in our mouths such as if it’s crunchy, soft, cold, hot, liquid, or solid. The function of taste buds are aided by olfactory sense.

The Nervous System and Diabetes: If you have an unhealthy nervous system you have a higher risk of developing diabetes. Diabetes can cause diabetic neuropathies, which is a family of nerve damages. About 60 to 70 percent of people with diabetes have some form of neuropathy. Diabetes can cause nerve damage, and

The Nervous System and Sickle Cell: Sickle cell can cause injuries to many parts of the body including the nervous system. Some medications used to treat sickle cell pain can be toxic to the nervous system.

The Nervous System and Heart Disease: When someone has heart disease it can cause stress. Which causes the sympathetic nervous system to sense danger, and that causes increase in heart rate.

The Nervous System and Urinary Tract Infection Diabetic neuropathy is an illness involving the nervous system, which can cause urinary tract infections.
