Answer:
Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.
Explanation:
Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are <u>packaged into vesicles</u> and <u>sent to the Golgi complex</u>, where it occurs the <em>final association of carbohydrates with proteins</em>. The Golgi complex <u>sends proteins to their different destinies</u>. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
The duodenum can therefore be subdivided into four segments: the superior, descending, horizontal, and ascending duodenum. ... The three regions of the small intestine are the duodenum, jejunum, and ileum. The jejunum is about 0.9 meters (3 feet) long (in life) and runs from the duodenum to the ileum.

Answer:
Here, the stimulus which is discussed in the question is the Suckling stimulus which is also known as Suckling reflex.
Suckling by a child stimulates the suckling reflex system. The stimulus (information) reaches to the Hypothalamus. Hypothalamus triggers the TRH (thyrotropin-releasing hormone) which further triggers the releases of the Prolactin (PRL) hormone by the Anterior Pituitary.
Finally, when Prolactin reaches the blood, it stimulates the Mammary glands which being stimulated, start to produce milk.
Explanation:
The main function of Prolactin is to produce milk. Prolactin production is mainly controlled by Hypothalamus. Prolactin hormone is produced in Pituitary, uterus, etc. The prolactin hormone production is also controlled by the estrogen.
- Prolactin regulation is also controlled by Dopamine and Oestrogen. Both of them regulates the onset and stoppage of prolactin production by sending the information to the pituitary gland. Dopamine mainly blocks the production when the level of prolactin is too high in the blood. Oestrogen mainly increases the production when the level of prolactin in the blood is too low.
- Not only Prolactin boost up the milk production but it also helps in maintaining the female's body metabolism, immune system, regulating the menstrual cycle, and regulating body fluid levels. In males, it increases sperm production.
