Asymmetric RNA Splicing The first genes with alternative RNA splicing were discovered in the 1970s.

When multiple combinations of exons are joined to make the mRNA, a procedure called alternative RNA splicing enables diverse protein products to be synthesized from a single gene. The frequency of various splicing alternatives is controlled by the cell as a way to regulate the production of different protein products in different cells or at different stages of development.

Alternative splicing can be haphazard, but more often it is controlled and acts as a mechanism of gene regulation. In eukaryotes, alternative splicing is widely recognized as a frequent process of gene control. One estimate place the proportion of human genes that are expressed as numerous proteins by alternative splicing at 70%.

which of the following tactile receptors is found in the dermal papillae? identification of tactile receptors which of the following tactile receptors is found in the dermal papillae? identification of tactile receptors tactile disc ruffini corpuscle free nerve endings tactile corpuscle

Answers

Meissner corpuscle or tactile corpuscle is the tactile receptor found in the dermal papillae.

Professor Georg Meissner and Professor Rudolf Wagner initially identified Meissner corpuscles, often referred to as Wagner-Meissner corpuscles or tactile corpuscles, as a subset of mechanoreceptors in 1852. These unique encapsulated nerve terminals transmit low-frequency vibration and fine touch sensations to the central nervous system from the dermal papillae of glabrous skin (CNS). Meissner corpuscles are crucial for somatosensory acuity, particularly in the palmar skin and digital extremities. This has clinical implications for diabetic neuropathy, peripheral neuropathy, and the aging-related deterioration of dermatological tactile sense.

Meissner corpuscles are ellipsoid mechanoreceptors that are situated 150 micrometres superficially within the dermal papillae. The corpuscles have a long axis that is perpendicular to the skin's surface and are between 20 and 40 micrometres in diameter and 80 and 150 micrometres in length. Less than three corpuscles per papilla, with one corpuscle every two to four dermal papillae. The site of genesis affects the receptors' size and density.

Answers

The following are likely to occur as a compensation of lactic acid buildup:

Decreased urinary pHIncreased H+ in bloodIncreased hyperventilationIncreased H+ selection

What is lactic acid?
Red blood cells and muscle cells are the principal producers of lactic acid. When oxygen levels are low, it develops when the body metabolizes carbohydrates for energy.

In the body, lactic acid serves three basic purposes:

as a significant source of energy for mitochondria as a starting point for the production of glucose as a signalling molecule
