What are the 4 types of tissue? | Connective, epithelial, muscle, nervous |
What are the 4 types of connective tissue? | Connective proper, cartilage, blood, bone |
What is the function of connective tissue proper? | Areolar (supply blood and soak up extra fluid) Adipose (insulate, protect, storage) Dense regular (tendons and ligaments) Dense irregular (surround organs) |
What is the function of cartilage? | Protects joints and bones |
What is the function of blood? | Transport oxygen and nutrients to the cells and carbon dioxide and waste out of the cells. |
What is the function of bone? | Support and protect the body. |
What is the function of tendons? | Connect muscle to bone |
What is the function of ligaments? | Connect bone to bone |
What makes up the appendicular skeleton? | Arms, legs, hips, scapula |
What makes up the axial skeleton? | Skull, chest, spine |
What is the function of osteoclasts? | Bone-destroying cells. Break down bone matrix for remodeling and release of calcium |
What is the function of osteocytes? | Mature bone cells |
What is the function of osteoblasts? | Bone-forming cells. Secrete minerals that make bones hard. |
Where are red blood cells made and where is this found? | Red bone marrow in spongy bone. |
What are the functions of the skeletal system? | movement, protection, support, storage, blood cell formation |
What is the lacunae and what is found in them? | Cavities containing mature bone cells (osteocytes). *Rings like trees* |
What is the canaliculi? | Tiny canals from the central canal through the rings/lacunae |
What is a process? | A boney outgrowth of a larger bone |
What is a simple fracture? | Bone is broken cleanly, ends to not penetrate skin. |
What is a closed reduction? | Nonsurgical realignment of broken bone end and splinting of bone |
What is a greenstick fracture? | A break common in children, bone splinters, break is incomplete. |
What is a compression fracture? | Bone is crushed, common in vertebral column |
What is a compound fracture? | Bone ends penetrate through the skin surface. |
What is an open reduction? | Surgical realignment of broken bone ends |
What is a spiral fracture? | A result of twisting forces. |
What is a depressed fracture? | Break of the cranial bone when the bone is "depressed" toward the brain. |
