which cells with in the islets of langerhans secrete insulin
Pancreatic islets It has been recognized that the cytoarchitecture of pancreatic islets differs between species.[8][9][10] In particular, while rodent islets are characterized by a predominant proportion of insulin-producing beta cells in the core of the cluster and by scarce alpha, delta and PP cells in the periphery, human islets display alpha and beta cells in close relationship with each other throughout the cluster.[8][10]
Thyrotropin-releasing hormone Following secretion, TRH travels across the median eminence to the anterior pituitary gland via the hypophyseal portal system where it stimulates the release of thyroid-stimulating hormone from cells called thyrotropes.[4]
Small intestine Absorption of the majority of nutrients takes place in the jejunum, with the following notable exceptions:
Nuclear membrane Exactly how the nuclear membrane reforms during telophase of mitosis is debated. Two theories exist[7]â€”
