Neural- when the nervous system directly = release of hormones (endocrine  system)

Functions of a hormone- chemical messages produced by cells to bind to  receptors on plasma membrane of other cells and altar metabolic functions  of cells

types of hormones

amino acid derivative

steroids

peptide/proteins

lock and key method

synergism- work together

antagonism- one works against

permissivness- a must be present for b to be fully effective what does iodine do: needed in order to make thyroid hormones types of hormones:

Cortical bone- compact

Trabecular bone- spongy

different kinds- long, flat, short, irregular, sesamoid

functions of bone: support, protection, red blood cell production , stores  calcium and provides levers for movement

Bone cells in order of remodeling:

1.osteoclasts- bone cutting cells

2.osteoblasts- bone building cells

3.osteocytes- mature osteoblasts that become calcified and part of the bone Remodling- happens one part at a time over the span of life rather than all at once

kinds of joints:

Fibrous- don’t move in the skull

cartilaginous- limited movement vertebrae

synovial- constant movement like fingers and wrist

synovial is most commonly affected by arthritis

Osteoarthritis- due to over use, wearing down of cartilage

Treatment- lowering excursive,Pharmacy agents

Rheumatoid arthritis- inflammation of synovial fluid, lining , membrane. gets  worse with age. Joints become red, swollen and painful. excessive fluid  production

Diagnosis with blood tests or x-rays If you want to learn more check out What is the supply of money?
