Stretch receptors
WebMuscle spindles are stretch receptors within the body of a skeletal muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via afferent nerve … Stretch receptors are mechanoreceptors responsive to distention of various organs and muscles, and are neurologically linked to the medulla in the brain stem via afferent nerve fibers. Examples include stretch receptors in the arm and leg muscles and tendons, in the heart, in the colon wall, and in the lungs. Stretch receptors are also found around the carotid artery, where they monitor blood pressure an…

WebMay 17, 2024 · If stretch receptors in the stomach are activated by the filling and distension of the stomach, a short reflex will directly activate the smooth muscle fibers of the stomach wall to increase motility to digest the excessive food in the stomach. No CNS involvement is needed because the stretch receptor is directly activating a neuron in the wall ...
WebArterial baroreceptors are stretch receptors that are stimulated by distortion of the arterial wall when pressure changes. The baroreceptors can identify the changes in both the average blood pressure or the rate of change in pressure with each arterial pulse. WebNov 15, 2024 · By mapping and manipulating the different types of sensory neurons that send signals from the gastrointestinal system back to the brain via the vagus nerve, the team showed that its...

When the bladder is full of urine, stretch receptors in the bladder wall trigger the micturition reflex. The detrusor muscle that surrounds the bladder contracts. The internal urethral sphincter relaxes, allowing for ...
WebIf arterial blood pressure suddenly falls, decreased stretch of the arterial walls leads to a decrease in receptor firing. The carotid sinus baroreceptors are innervated by the sinus nerve of Hering, ... The carotid sinus receptors respond to pressures ranging from 60 to 180 mmHg (Figure 2). Receptors within the aortic arch have a higher ...
