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.
