Transcript of Nervous System

Nervous System Main Parts Neurons
The Brain
Spinal Cord
How do they work together? The neurons are cells that make up the nervous system, They are the things that carry electrical messages
The Neurons run up the spinal cord and attach to the brain stem. Some messages are processed by the spinal cord but most information is sent on to the brain. After the signals go to the brain
the brain tells you what to do. this happens in the largest part of the brain. this part controls the vision touch and other senses. How does it work with other systems? Skeletal System
Bones provide calcium that is essential for the proper functioning of the nervous system.The skull protects the brain from injury.The vertebrae protect the spinal cord from injury.Sensory receptors in joints between bones send signals about body position to the brain.The brain regulates the position of bones by controlling muscles. Cardiovascular System
Endothelial cells maintain the blood-brain barrier.
Baroreceptors send information to the brain about blood pressure.
Cerebrospinal fluid drains into the venous blood supply.
The brain regulates heart rate and blood pressure. Muscular System
Receptors in muscles provide the brain with information about body position and movement.The brain controls the contraction of skeletal muscle.
The nervous system regulates the speed at which food moves through the digestive tract.
Endocrine System
Hormones provide feedback to the brain to affect neural processing.Reproductive hormones affect the development of the nervous system.The hypothalamus controls the pituitary gland and other endocrine glands. Lymphatic System
Hormones provide feedback to the brain to affect neural processing.Reproductive hormones affect the development of the nervous system.The hypothalamus controls the pituitary gland and other endocrine glands. Respiratory System
The brain monitors respiratory volume and blood gas levels.The brain regulates respiratory rate. Digestive System
Digestive processes provide the building blocks for some neurotransmitters.The autonomic nervous system controls the tone of the digestive tract.The brain controls drinking and feeding behavior.The brain controls muscles for eating and elimination.The digestive system sends sensory information to the brain. Reproductive System
Reproductive hormones affect brain development and sexual behavior.The brain controls mating behavior. Urinary System
The bladder sends sensory information to the brain.The brain controls urination. Integumentary System
Receptors in skin send sensory information to the brain.The autonomic nervous system regulates peripheral blood flow and sweat glands.Nerves control muscles connected to hair follicles. Diseases 5.3 million Americans are living with Alzheimer’s disease Alzheimer's destroys brain cells, causing memory loss. Affects more women than men. Has no current cure. Alzheimer Disease Tips to keep your nervous system healthy 1. Exercise your nervous system on a daily basis.
2. Ensure optimal nutritional support for your nervous system.
Fun Facts Only four percent of the brain's cells work while the remaining cells are kept in reserve.
The Nervous system transmits messages to the brain at the speed of 180 miles per hour.
