Endocrine Glands: Hormones and their Regulations
Endocrine glands are specialized organs that secrete hormones directly into the bloodstream. These hormones regulate various physiological processes, including growth, metabolism, and mood. Unlike exocrine glands, which release substances through ducts, endocrine glands are ductless. Key endocrine glands include the pituitary, thyroid, adrenal glands, and the pancreas. Each gland produces specific hormones, such as insulin … Read more

Location Structure Parts and Functions Summary The human brain, housed within the cranial cavity, is a complex organ composed of the cerebrum, cerebellum, and brainstem. Each part … Read more
Terms of Developmental Biology
Developmental biology is the field of biology that studies the process by which organisms grow and develop. Some of the Terms of Developmental Biology: Blastula: The early stage of the embryo, characterized by a hollow sphere of cells. Blastocoel: The fluid-filled cavity inside the blastula. Gastrula: The stage following the blastula, during which the three … Read more
Lac Operon: Genes, Regulation and Structure
Lac Operon (Prokaryotes) Discovered By: François Jacob and Jacques Monod in 1961 (1) Genes Housekeeping genes: “Always cell are on” . Some genes in bacterial cells are important to the life of the cell. Thus their expressions occur constitutively and not subject to regulation. Inducible gene: “Normally off”. Because it induces or switch on the gene. … Read more
