- The presence of calcium in the sarcoplasm is directly responsible for exposing the binding sites on actin.
- Rigor mortis occurs after death because detachment of crossbridges does not occur due to the lack of ATP
<h3>What is Sarcoplasm?</h3>
This is defined as the the cytoplasm of striated muscle cells in living organisms .When calcium is present, the binding sites on actin are exposed.
Rigor mortis occurs after death and involves stiffening of the muscle tissue because detachment of cross bridges does not occur due to the lack of ATP.

Neurons in the hypothalamus regulate the activity of secretory cells in the anterior pituitary gland by releasing hormones. Pituitary gland basically store the hormones which is produce by the hypothalamus.
Hypothalamus connect the nervous and endocrine systems by way of the pituitary gland. Both are connected directly to the pituitary gland by a thin stalk which is called infundibulum.
Its main function is to secrete releasing hormones and inhibiting hormones that stimulate the production of hormones in the anterior pituitary. FSH and LH both are produce and secret gonadotropins which regulated by the hypothalami releasing hormone, GnRH. These are the releasing hormones which control the release of another hormone.
