Select the correct location on the image. An injury to which marked region would hamper the sleep-wake cycle?

Soloha48 [4]

I attached the image related to your concerned question.

In theory, the part of the brain that is responsible for the sleep wake cycle is the hypothalamus; specifically, the ventrolateral preoptic nucleus of the hypothalamus. In the image, the location of the hypothalamus is pointed by the green square.

The ______ system is assisted by the lymphatic system and the physical barriers of the skin and gastrointestinal tract.

mezya [45]

Answer:

The correct answer is- Immune system

Explanation:

There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.

The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.

Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.

So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.

Adaptive immunity comprises two branches: humoral immunity and cellular immunity. What are the characteristics of each of the tw

kotegsom [21]

Answer:

Adaptive or acquired immunity is that we acquire throughout our lives through vaccines (active), breast milk (passive) or injection of specific artificial or natural antibodies to a certain pathogen (passive).

The two great arms of this immunity are the humoral and the cellular.

The humoral refers to the cytokines and immunomodulatory molecules that are responsible for transmitting fundamental messages between defense cells in order to coordinate the destruction of the pathogen between them.

Instead, cellular immunity speaks about cell lineage such as b, t, tcd4 lymphocytes, natural killers, plasmacytes, etc.

It can be said that the humoral factor is the one that coordinates the pathways and the relationships between the cells of the acquired immunity, both are important because the two need each other for adaptive immunity to work.

Explanation:

Examples of the humoral factor: pro and anti inflammatory cytokines, interleukins, complement chain, antibodies, TNF alpha, beta, etc.

Examples of cellular factor: plasmacyst, b lymphocyte, t lymphocyte, NT lymphocyte
