They are called prostaglandins.
Prostaglandins are modified fatty acids that are produced by a wide range of cells. They generally affect only nearby cells and tissues, and thus are known as "local hormones."
Benign is a tumor that doesn't spread to nearby tissues.
Local hormones produced by most body tissues are called autocrine and paracrine hormones. Autocrine hormones act on the same cell that produced them, while paracrine hormones act on nearby cells within the same tissue.
True. Epithelial tissues do not contain blood vessels, which is why they rely on diffusion from nearby blood vessels in connective tissues for their nutrient and oxygen supply.
Yes. It is usually seen around the genital region and other tissues nearby.
An allelochemical is a chemical which has allelopathic affects - that which is able to release a toxin to suppress growth of nearby competing plants.
Osteoarthritis primarily affects the joints in the skeletal system. Commonly affected structures include the cartilage, bone, synovium, and surrounding tissues in the joints, leading to pain, stiffness, and reduced mobility. Over time, osteoarthritis can also impact nearby ligaments and muscles.
The medical term for tissues without their own blood supply is avascular tissue. These tissues rely on diffusion to obtain nutrients and oxygen from nearby blood vessels. Examples include cartilage and cornea.
Benign brain tumors do not infiltrate nearby tissues but can cause severe pain, permanent brain damage, and death
Cancer is best described as an uncontrolled growth of abnormal cells that can invade nearby tissues and spread to other parts of the body.
