Tibial tuberosity

A primary function of the skeletal system is cushioning abdominal organs such as the kidneys. contracting muscles. absorbing the shock of unexpected rapid body movements. facilitating transmission of nerve impulses. maintaining the normal concentrations of calcium and phosphate ions in body fluids.

maintaining the normal concentrations of calcium and phosphate ions in body fluids.

Which of the following matches the cell with its function? osteocytes: resorption osteoclasts: ossification osteoblasts: ossification osteoblasts: maintenance of normal bone structure

osteoblasts: ossification

In the skeletal system, compact bone is usually located where stresses come from a limited range of directions. where bones are not heavily stressed. in direct contact with articular cartilages. only in a narrow ring around the diaphysis of long bones. where stresses arrive from many directions.

where stresses come from a limited range of directions.

Jason fractured his pisiform bone in an accident. What part of his body is injured? wrist ankle shoulder leg skull

Name bone that articulates with the proximal end of the tibia. Calcaneus Femur Fibularis Fibula

Femur

Which of the following occurs in intramembranous ossification? Ossification centers are formed as blood vessels and osteoblasts enter the centers of the epiphyses. As the bone enlarges, osteoclasts break down some of the spongy bone and create a marrow cavity. Hyaline cartilage model forms. Periosteum forms a collar around the cartilage. Fibrous connective tissue is converted to bone tissue, which first resembles spongy bone.

Identify the bone found lateral to the tibia. Fibularis Femur Calcaneus Fibula

Identify the anatomical landmark resulting in a noticeable bump found on the medial surface of the ankle. Medial condyle Medial malleolus Styloid process Lateral malleolus

Medial malleolus

Your doctor suggests that you increase your calcium intake to maintain your healthy bones. You do not understand why the doctor suggested this since you are a healthy 32-year-old. What was the doctor's reasoning? The doctor is afraid that you will fall and break a bone. The increased calcium intake will then increase your vitamin D blood level. Calcium intake will increase the activity of osteoblasts, causing more bone to be formed. As you get older you are more prone to arthritis, and calcium reduces that problem. You are at an age where calcium levels in the bone may start to subside, producing weaker bones later in life.

You and your twin sister, both 18 years of age, were in a car accident. She had a clean break across the humerus and the upper arm bone-no bleeding, no break in the skin. However, you have a very messy break of the distal tibia in the lower leg, requiring pins to be inserted. Which statement is true regarding the differences in your break and your sister's break? Your damage is called a fracture, whereas hers is called a break. You will be given antibiotics to reduce bacterial infection, whereas your sister will not. You are given calcium to take but your sister is not. Your break will not heal whereas her fracture will heal fine. Since her fracture did not penetrate through skin, it will not show up on an X-ray, whereas yours will.

You will be given antibiotics to reduce bacterial infection, whereas your sister will not.
