The branching pieces of bone in spongy bone are called:


a. lamellae.
b. lacunae.
c. osteoclasts.
d.trabeculae.

Verified step by step guidance

1. Understand the structure of spongy bone, which is also known as cancellous bone, and its role in the skeletal system.
2. Identify the key components of spongy bone, focusing on the network-like structure that provides support and flexibility.
3. Recall that spongy bone is characterized by a meshwork of branching bone pieces.
4. Review the definitions of the given options: lamellae, lacunae, osteoclasts, and trabeculae.
5. Determine which term specifically refers to the branching pieces of bone in spongy bone.

Key Concepts

Spongy Bone Structure

Spongy bone, also known as cancellous bone, is a type of bone tissue characterized by a porous, lattice-like structure. This structure provides strength while minimizing weight, making it essential for supporting the body's framework. The spaces within spongy bone are filled with bone marrow, which is crucial for blood cell production.

Trabeculae

Trabeculae are the small, rod-like or plate-like structures that form the framework of spongy bone. They create a network that supports the bone's overall structure and helps distribute stress and strain during weight-bearing activities. Trabeculae are essential for maintaining the integrity and functionality of spongy bone.

Bone Cells

Bone tissue is maintained by various types of cells, including osteoblasts, osteocytes, and osteoclasts. Osteoblasts are responsible for bone formation, osteocytes maintain bone tissue, and osteoclasts are involved in bone resorption. Understanding these cells is crucial for comprehending how bones grow, repair, and adapt to stress.
