Study Notes

Bone Tissue Overview

Bone is categorized as connective tissue, vital for various body functions.
The skeletal system functions include protection, support, movement, blood cell formation, but does not regulate sodium ion homeostasis.

Bone Structures and Types

The skeleton serves as an organ system.
Yellow marrow is primarily a fat storage site, while red marrow is responsible for blood cell production.
Two main types of osseous tissue: spongy and compact.

Bone Cells and Functions

Osteocytes maintain bone health, while red marrow produces blood cells.
Osteoblasts are involved in building bone, whereas osteoclasts break down bone tissue.
Yellow marrow serves as a fat storage area.

Bone Formation and Remodeling

Bone formation is known as ossification, and osteoclasts function primarily in bone resorption.
Both osteoblasts and osteoclasts work simultaneously during the process of bone remodeling.
An increase in osteoblast activity results in larger and heavier bones.

Bone Density and Health

Bone density can decrease due to inactivity, such as lying in bed for an extended period.
A comatose individual for six months would show less than normal bone density for their age.
Overactivity of osteoclasts can lead to significant bone loss and potentially osteoporosis.

Bone Composition

Bones are composed of osteocytes for maintenance and collagen for flexibility.
Minerals like calcium and phosphate provide strength to bones.
The extracellular matrix of bone primarily consists of inorganic materials.

General Facts about Bone Tissue

Bone tissue is dense and hard, serving multiple functions including support, protection, movement, and storage.
Red marrow is incorrectly stated to be a site of triglyceride storage; this function belongs to yellow marrow.
lactose intolerance is a significant contributor to weak or brittle bones.

Summary of Bone Cell Activities

An adult's requirement for blood cell formation is generally met by remaining red marrow and other body sites.
If both osteoblasts and osteoclasts were doubled in activity, the overall impact on bone would be negligible.
Strong osteoblast activity increases bone diameter and enhances strength.
