Answer:

b. Melanocytes-protect cells in the dermis from damaging effects of sun's rays

Explanation:

Keratinocytes are responsible for the forming tight junctions with nerves of skin. They keep Langerhans cells of epidermis and lymphocytes of dermis in place.

<u>(Option A is incorrect). </u>

Melanocytes are the cells of the neural crest origin. In epidermis, they form association closely with the keratinocytes via dendrites. Melanocytes are responsible in skin pigmentation.

<u>(Option B is correct). </u>

Basal cells are undifferentiated and proliferating cells. For the normal skin homeostasis, the daughter cells from basal cell layer migrate upward and begin process of the differentiation.

<u>(Option C is incorrect). </u>

Merkel cells are located in basal epidermal layer of skin. Merkel cells are  essential for the light touch sensation and are found in the skin of vertebrates.

<u>(Option D is incorrect). </u>

Someone explain classical conditioning from Ivan Pavlovym to me please???????
pashok25 [27]

Answer:

Discovered by Russian physiologist Ivan Pavlov, classical conditioning is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus.

Explanation:

The most important thing to remember is that classical conditioning involves automatic or reflexive responses, and not voluntary behavior (that's operant conditioning, and that is a different post). What does this mean? For one thing, that means that the only responses that can be elicited out of a classical conditioning paradigm are ones that rely on responses that are naturally made by the animal (or human) that is being trained. Also, it means that the response you hope to elicit must occur below the level of conscious awareness - for example, salivation, nausea, increased or decreased heartrate, pupil dilation or constriction, or even a reflexive motor response (such as recoiling from a painful stimulus). In other words, these sorts of responses are involuntary.

The basic classical conditioning procedure goes like this: a neutral stimulus is paired with an unconditional stimulus (UCS). The neutral stimulus can be anything, as long as it does not provoke any sort of response in the organism. On the other hand, the unconditional stimulus is something that reliably results in a natural response. For example, if you shine a light into a human eye, the pupil will automatically constrict (you can actually see this happen if you watch your eyes in a mirror as you turn on and off a light). Pavlov called this the "unconditional response." (UCR)

As soon as the neutral stimulus is presented with the UCS, it becomes a conditional stimulus (CS). If the CS and UCS always occur together, then the two stimuli would become associated over time. The response that was initially produced in response to the UCS would also be produced in response to the CS, even if it was presented alone. Pavlov called this the "conditional response." (CR)

To make this a bit more concrete, we'll use Pavlov's dogs as an example. Before learning took place, the dogs would reliably salivate (UCR) when given meat powder (UCS), but they gave no response to the ringing of a bell (neutral). Then Pavlov would always ring a bell just before he would present the dogs with some meat powder. Pretty soon, the dogs began to associate the sound of the bell with the impending presence of meat powder. As a result, they would begin to salivate (CR) as soon as they heard the bell (CS), even if it was not immediately followed by the meat powder (UCS). In other words, they learned that the bell was a reliable predictor of meat powder. In this way, Pavlov was able to elicit an involuntary, automatic, reflexive response to a previously neutral stimulus.
