Human Anatomy Chapter 5 Quiz

Study Notes

Bone Cells and Types

Osteocytes are the bone-destroying cells responsible for bone resorption and maintenance of bone tissue.
Compact bone is a dense and solid type of bone that provides strength and structure to the skeletal system.
Cancellous bone, also known as spongy bone, has a porous structure that aids in weight reduction and flexibility.

Vertebrae and Joints

The atlas is the first cervical vertebra, allowing the nodding of the head.
Irregular bones, such as the vertebrae in the spine, have complex shapes and provide support and flexibility.
The knee is classified as a hinge joint, allowing movement primarily in one plane (flexion and extension).
Synovial joints are recognized as the most mobile type of joint in the human body, allowing a wide range of movements.

Bone Structure and Function

The periosteum is the outer covering of bone, serving as a protective layer and an attachment point for muscles.
The epiphysis refers to the end part of long bones, contributing to joint formation and articulation.
The diaphysis is the shaft of long bones, providing structural support and housing the medullary cavity.
The ilium is the largest portion of the coxal bone, forming part of the hip structure.

Types of Marrow and Movement

Yellow marrow is primarily involved in fat storage, found mostly in the diaphysis of long bones.
Flexion is a type of movement that decreases the angle between body parts, essential for various physical activities.
Abduction is the movement of a limb away from the midline of the body, contributing to various bodily motions.

Joint Stability and Shock Absorption

Menisci are cartilaginous structures in the knee that absorb shock and stabilize joint movement.
Cruciate ligaments form an X inside the knee joint, stabilizing it during movement.
Sutures are a type of immovable joint found between flat bones of the skull, allowing minimal movement for protection.
The sacrum forms the base of the spine, consisting of five fused vertebrae that support pelvic structures.

Weight Bearing

The body of vertebrae plays a crucial role in weight-bearing, supporting the impact of forces and maintaining posture.
Short bones typically have a composition of mostly spongy bone, making them lightweight yet durable for flexibility and shock absorption.
