What are the main 2 parts of the long bones? | Diaphysis (middle shaft of bone) and epiphysis (ends of the bone). |
What is the layer of cartilage called that separates the epiphyses from the diaphysis? It eventually is replaced with bone when it is done growing. | Epiphyseal plate converts to epiphyseal line. |
What are the two cells that have opposite functions that allow the bone to grow in diameter. These cells also help with the reasorption and calcium depositing. | Osteoblast (mineralizes bone tissues) and osteoclast (erodes bone). |
Which two hormones play a role in the homeostasis of calcium levels in the blood? | Parathyroid hormone (released by parathyroid, stimulate osteoclasts to breakdown bone matrix to release Ca in blood, also increase renal absorption of Ca from urine) and Calcitonin (released from thyroid, stimulate osteoblasts and inhibit osteoclasts) |
What are the 5 types of bones? | Long bones, short bones, irregular bones, flat bones, and sesamoid bones. |
What is the axial skeleton? | The skull, vertebral column, and the sternum and ribs (80 bones total). |
What is the appendicular skeleton? | The upper and lower extremities (126 bones total). |
Which metacarpal bone is the most freely movable joint amongst the metacarpal bones? | The thumb metacarpal (allows for the thumb to oppose each finger, giving humans great dexterity to manipulate small objects). |
What are the 4 major tissue types of the body? | Epithelial, connective, muscle, and nervous tissue. |
What is the layer called that acts as a gluelike connection between a sheet of cells and the underlying connective tissue? | Basement membrane |
