What do the receptor cells for hearing static equilibruim and dynamic equilibrium have in common?
The three have this in common: - Balance - Stimulation of hair cells that generate impulse carried by the vestibular branch of cranial VIII.
What does the phrase density of receptor cells mean?
Density of receptor cells are the amount of receptor cells in a specific area of the body. This could be in the lips.
What are the non specific drug effect?
Hase not specific receptor
Compare two ways that the binding of a signal molecule to a receptor protein causes a change in activity the receiving cell?
1. Insulin binding to insulin receptor tyrosine kinase on hepatocyte: increased glucose uptake, increased glycogen and fatty acid production and decreased catabolism in general (decreased gluconeogenesis, lipolysis, and proteolysis). Insulin binding causes receptor dimerization and self-phosphorylation. Phosphorylated receptor recruits scaffold proteins and downstream target proteins and phosphorylate them. Phosphorylated target proteins serve as kinases and activate or deactivate other proteins by phosphorylation, effecting appropriate effects. 2. Erythropoietin binding to EPO cytokine receptor on Common Myeloid Progenitor cell: eventual differentiation into erythrocyte. Cytokine receptor induces the Jak/STAT pathway resulting in altered gene expression by transcription factors, drastically changing the function and morphology of the cell.
Which is more sensitive over skin temperature or touch and why?
Touch ... the number of receptor cells.
What is the receptor for equilibrium?
The Macula is the receptor for static equilibrium.
What is the sensory receptor for static equilibrium?
macula
What are the receptor organs for equilibrium?
macula for static equilibrium and cristae for dynamic equilibrium. All are found in the inner ear.
What are the receptor cells involved in dynamic equilibrium?
cristae
Which part of a reflex arc monitors body conditions?
Sensory Receptor
which of the following are responsible for recognizing a change to the system?
receptor cells - apex
Which of the following drugs is an example of a selective 5-HT receptor agonist?
midril
Are semicircular canals the same as semicircular ducts?
No. Semicircular canals are located in the vestibule of the ear and are membranous that contain receptor cells; semicircular ducts house dynamic equilibrium receptors and contain an enlarged region and a receptor region and that respond to angular motion.
What is the cupula of the ear?
which receptor is involved in the sense of rotational equilibrium
Equilibrium receptor found within ampullae of semicircular canals?
The semicircular canal is found in the inner ear and is responsible for individuals being able to keep their balance. There is a sort of bulbous structure at the end of the semicircular canal called the ampulla which is where the receptors of equilibrium are located.
Contains the cristae ampullaris?
semicircular ducts have an enlarged swelling at one end called an ampulla, which houses an equilibrium receptor region called a crista ampullaris
What is receptor internalisation?
Receptor internalization is the process by which cell surface expressed receptors are monoubiquitinated following ligand-induced activation, and subsequently taken up into the endocytic vesicles to the lysosome. The receptor will either be degraded or brought back to cell membrane were it is again able to interact with its ligands. Receptor internalization serves as a mechanism to downregulate receptor signaling upon agonistic ligand stimulation.
