Identify A,B,C and D,E

Answer

To identify the components labeled A, B, C, D, and E in the provided diagram of the pituitary gland, we can follow these steps:

1. **Identify A**: The first part, labeled A, corresponds to the anterior pituitary lobe. This lobe is responsible for the secretion of various hormones that regulate important bodily functions.

2. **Identify B**: The second part, labeled B, is the posterior pituitary gland. This part of the pituitary gland stores and releases hormones produced by the hypothalamus.

3. **Identify C**: The third part, labeled C, represents the hypothalamus. The hypothalamus is a critical brain region that links the nervous system to the endocrine system via the pituitary gland.

4. **Identify D**: The fourth part, labeled D, consists of hypothalamic neurons. These neurons are responsible for sending signals to the pituitary gland, influencing its hormone secretion.

5. **Identify E**: The fifth part, labeled E, is a bundle of capillaries. These capillaries are involved in the blood supply to the pituitary gland and facilitate the transport of hormones.

### Summary of Identifications:
- A: Anterior Pituitary Lobe (Adenohypophysis)
- B: Posterior Pituitary Gland (Neurohypophysis)
- C: Hypothalamus
- D: Hypothalamic Neurons
- E: Bundle of Capillaries
