Nervous System By: Celinda Liu, Rachel Liang, Melissa Fan, Jennifer Chung, Eric Gjana, Jacky Cai
The nervous system is one of the major regulatory systems of the body maintaining homeostasis. Its functions are, monitoring the body’s internal and external environments. Another function: integrate sensory information. And, direct or coordinate the responses of other organ systems to the sensory input. Vocabularies- Central Nervous system Peripheral Nervous system Brain Spinal Cord Nerves Neurons Definitions and functions and its parts. (Celinda)
Definitions continues…. • Central Nervous System- consists of brain and spinal cord • Peripheral Nervous System- consists of sensory organs, such as eyes, ears, and body nerves • Spinal Cord- cord of nerve tissue in the spinal column • Nerves- cord like fiber carrying impulses to and from the brain. • Neurologic- medical that deals with the nervous system and disorders affecting it.
Most of the diseases and disorders of the Nervous System are located in the brain itself and its surrounding structures. Some other diseases lead to closure of some of the blood vessels of the brain. A spinal cord disease associated with injury or compression of the spinal nerves. A disorder is the pressure inside or around the skull. It also involves the blood flow to the brain. If brain cells die, it causes a brain attack or stroke. Vocabularies- Inadequate Symptom Tumors Seizures Epilepsy Neurologic Meningitis Disorders and Diseases of the Nervous System (Rachel)
Diseases Multiple Sclerosis- This is a disease of the central nervous system that is an unpredictable condition that can be relatively benign, disabling or devastating, leaving the patient unable to speak, walk, or write. Spine Disease- associated with injury or compression of the spinal cord or spinal nerves. Brain Tumor- an abnormal growth that involves the brain itself or its surroundings structures. Two general classes: 1. Intra- axial tumors- tumors which grow with in the substance of the brain. 2. Extra- axial tumors- tumors that originate outside of the actual tissues of the brain, but can involve the brain because of their close proximity. Disorders Brain attack (stroke)- Happens when brain cells die because of inadequate blood flow to the brain Intracranial pressure (ICP)- The pressure inside the skull. Examples of Disorders and Diseases
Definition continues… • Inadequate- Not enough or not good enough • Symptom- setting that shows that you have on illness • Tumors- an abnormal lump or mass of tissue in the body • Seizures- a sudden attack of illness or a spasm • Epilepsy- a disease of the brain that causes a person to have sudden black outs or convulsions.
The two major parts of the nervous system is the central nervous system and peripheral nervous system. The central system controls your body or the spinal cord. The peripheral nervous system connects to your organ. Identify the Major parts included in your systems ( Melissa) Vocabularies- Central nervous system- brain Peripheral nervous system- vein
The important of your system and why it is vital to your body’s Survival (Jennifer) • Brain is important because it helps us think, feel, remember, and imagine. The brain keeps the body in order. Without your brain, we can’t do anything. Brain helps us control our body. It helps us keep working.
