The Sympathetic
The vascular system signals for blood vessels to constrict or dilate. The nervous system, such as the spine, and the brain, work together to help blood vessels respond accordingly.
The sympathetic system causes the vessels to constrict (shut blood to core systems) and is often called the fight or flight response. The parasympathetic system causes the vessels to relax and is often called the feed and breed response.
The sympathetic nervous system can increase blood pressure by causing blood vessels to constrict and the heart to beat faster. This response is part of the body's fight-or-flight reaction to stress or danger.
Dendrites receive signals in the nervous system.
An increase in sympathetic nervous system activity can lead to higher blood pressure. This is because the sympathetic nervous system releases hormones like adrenaline, which can cause blood vessels to constrict and the heart to beat faster, resulting in elevated blood pressure.
The sympathetic nervous system increases blood pressure by releasing adrenaline, which causes blood vessels to constrict and the heart to beat faster and stronger. This response helps the body prepare for fight or flight situations.
Nervous system sends controlling signals to respiratory system via nerves of autonomic system, these signals arise from breathing center of medulla .
neurons
There are billions of nerves in the nervous system. The nervous system is responsible for transmitting signals throughout the body.
The motor neurons of the peripheral nervous system send signals from the central nervous system to the muscles, causing them to contract and move. These signals are transmitted through neurotransmitters released at the neuromuscular junction.
Neurons are the cells that transmit electrical signals through the nervous system to various organs in the body. They are specialized cells that can receive, process, and transmit information via electrical and chemical signals.
