Types of Bones in the Human Skeletal System: Structure, Classification & Functions B.Pharmacy 1st Semester 2022 (2021-2022) Previous Year's Question Papers/Notes Download - HK Technical PGIMS

This document provides a detailed classification of human bones, covering their structure, functions, and anatomical significance in the skeletal system. Key highlights include:

1. Bone Types & Features:

• Long Bones (e.g., femur, humerus): Support weight and enable movement.

• Short Bones (e.g., carpals, tarsals): Provide stability and shock absorption.

• Flat Bones (e.g., skull, ribs): Protect vital organs and anchor muscles.

• Irregular Bones (e.g., vertebrae, hyoid): Complex shapes for specialized functions.

• Sesamoid Bones (e.g., patella): Embedded in tendons to reduce friction.

2. Functional Roles:

• Support & Movement: Leverage for muscle attachment.

• Protection: Shield organs (e.g., skull for brain, ribs for heart/lungs).

• Hemopoiesis: Blood cell production in bone marrow.

• Mineral Storage: Calcium and phosphate homeostasis.

3. Anatomical Distribution:

• Upper/Lower Extremities: Long bones (clavicle, tibia) and short bones (phalanges).

• Axial Skeleton: Flat (sternum) and irregular bones (vertebrae).
