A bone region has a lattice-like structure, contains marrow in its spaces, and helps distribute forces. Which type of bone tissue is it?
- A
Dense tissue forming the strong outer layer of most bones
- B
Lattice-like tissue inside bones, with spaces that contain marrow and help distribute forces
- C
A blood-vessel-rich covering on most of the bone's outer surface
- D
Smooth tissue covering bone ends where they meet at joints
Which bone cells help maintain and regulate bone tissue? Enter the plural cell name.
A tough, blood-vessel-rich covering coats most of a bone's outer surface. This covering is the .
Bone's collagen framework helps it resist pulling forces, while its mineral content helps it resist compression. Is this statement true or false?
- A
True
- B
False
During bone remodeling, which cells break down existing bone tissue?
- A
Osteoblasts
- B
Osteocytes
- C
Osteoclasts
- D
Chondrocytes
Two skull bones are joined by dense connective tissue and allow little or no movement. Which structural class of joint best describes their connection?
- A
A synovial joint, because all joints that connect bones have a fluid-filled cavity
- B
A fibrous joint, because dense connective tissue joins the bones and permits little or no movement
- C
A cartilaginous joint, because cartilage joins the bones and permits the greatest range of movement
- D
A synovial joint, because ligaments prevent all movement between the bones
What is the anatomical term for the structure that attaches a skeletal muscle to a bone? Enter the singular term.
The production of red blood cells, many white blood cells, and platelets in red bone marrow is called .
Which statement best explains how the hip joint's structure relates to its function?
- A
The hip permits broader movement than the shoulder because its joint is less stable.
- B
The shoulder is deeper and more stable than the hip to support body weight.
- C
The hip's deep, stable joint helps support body weight.
- D
The hip and shoulder have identical structures and movement ranges.
Select all statements that correctly describe the roles of blood cells produced in red bone marrow.
- A
Red blood cells transport oxygen.
- B
White blood cells contribute to immune defense.
- C
Platelets help blood clot.
- D
Platelets transport oxygen.
- E
White blood cells are the main cells responsible for blood clotting.
Select all statements that correctly describe the structures and functions of a synovial joint.
- A
Articular cartilage reduces friction between the bone ends.
- B
Synovial fluid lubricates the joint surfaces.
- C
A capsule encloses the joint.
- D
Ligaments help hold the bones together and limit excessive movement.
- E
The joint cavity is filled with bone marrow.
Explain how the biceps, triceps, bones, and elbow joint work together to bend and straighten the arm. Include the role of the bone as a lever and the joint as a pivot.
True or false: Skull sutures are fibrous joints that allow little or no movement.
- A
True
- B
False
What is the anatomical name for the shaft of a typical long bone?
A bone must withstand both pulling and compressive forces. Which description best explains how its collagen framework and mineral salts contribute?
- A
Collagen gives bone hardness, while mineral salts help it resist pulling forces.
- B
Collagen helps bone resist pulling forces, while mineral salts help it resist compression.
- C
Both collagen and mineral salts primarily help bone resist pulling forces.
- D
Both collagen and mineral salts primarily help bone resist compression.
A sample of marrow is described as being rich in fat and serving mainly as an energy store. Which type of marrow is it?
- A
It produces red blood cells, many white blood cells, and platelets.
- B
It lubricates the surfaces of synovial joints.
- C
It is richer in fat and mainly stores energy.
- D
It forms the dense outer layer of most bones.
When the body needs minerals, which skeletal function can help supply them?
- A
It produces the force that muscles use to move the body.
- B
It stores minerals such as calcium and phosphate for release when needed.
- C
It makes synovial fluid for all the body's joints.
- D
It carries oxygen from the lungs to body tissues.
A joint has a capsule around a fluid-filled cavity and allows a wide range of movement. Which description best explains how its structures help movement remain smooth?
- A
Dense connective tissue joins the bones, and movement is little or absent.
- B
Cartilage joins the bones and permits only limited movement.
- C
A fluid-filled cavity is enclosed by a capsule, with cartilage and fluid supporting smooth movement.
- D
A marrow-filled cavity between the bones permits the greatest range of movement.
