OSTEOLOGÍA VETERINARIA || CLASE # 3 || ANATOMÍA VETERINARIA

Introduction to Osteology

Overview of the Course

• The video is presented by Allison, a veterinarian, introducing the topic of osteology as part of her veterinary anatomy course.

• Viewers are encouraged to watch previous videos on topographical terms in veterinary anatomy for better understanding.

Definition and Functions of the Skeleton

• The skeleton is defined as a hard framework that supports and protects soft tissues in animals.

• Key functions include support, protection, metabolic functions, and storage of calcium and phosphorus.

Divisions of the Skeleton

Types of Skeleton

• The skeleton is divided into axial (skull, vertebral column, ribs, sternum), appendicular (limb bones), and splanchic (bones developing within soft organs).

Components Explained

• Axial skeleton includes the skull and spine; appendicular consists of thoracic and pelvic limb bones.

Bone Classification

Types of Bones

• Bones are classified into long bones (e.g., femur), flat bones (e.g., scapula), short bones (e.g., vertebrae), and irregular bones (e.g., base of the skull).

Characteristics

• Long bones have cylindrical shapes with widened ends; flat bones provide muscle attachment areas; short bones vary in shape.

Structure of Bone

Composition Details

• Bone is a living tissue containing blood vessels, nerves, and an outer membrane called periosteum.

Healing Process

• When fractured, bone can heal itself; however, inactivity leads to weakness.

Bone Functionality

Vascularization and Nerve Supply

• Bones contain numerous blood vessels with two main artery types: periosteal and medullary. Nerves accompany these vessels.
