Skeletal System Flashcards
from Greek word meaning “dried-up body”
Skeleton
The internal frame of the body
Skeletal System
Bones of the Skeleton
▪ Joints
▪ Cartilages
▪ Ligaments (Fibrous cords that bind the bones
together at joints)
Two divisions of Skeleton
Axial Skeleton
Appendicular Skeleton
Bones that form the longitudinal axis of the body
Axial Skeleton
The Bones of the Limbs and grindles that attach
them to the Axial Skeleton
Appendicular Skeleton
The study of bone structure and the treatment f bone
disorder
Osteology
The construction of new bone tissue and breaking
down of old bone tissue.
Remodeling
Functions of the Skeletal System
Body support
Protection
Movement
Storage
Blood Cell Production
Triglyceride storage
for bearing weight; major supporting tissue of
the body.
Bone
provides a firm yet flexible support within
certain structures, such as the nose, external ear,
thoracic cage, and trachea.
Cartilage
strong bands of fibrous connective
tissue that hold bones together.
Ligaments
skeletal
muscles attach to bones
Tendons
formed where two or more bones come
together, allow movement between bones.
Joints
covers the ends of bones within
some joints, allowing the bones to move freely
Smooth cartilage
allow some movement between bones
but prevent excessive movements.
Ligaments
Minerals stored in our bones
(Calcium and Phosphorus)
produces
red blood cells, white blood cells, and platelets, a
process called hemopoiesis.
Red Bone Marrow
Blood making, blood cell
formation.
Hemopoiesis
consists mainly of adipose
cells, which store triglycerides
Yellow bone marrow
Components of the Skeletal System (Composition)
Bones
Joints
Cartilage
Ligaments
Tendons
The adult skeleton is composed of how many bones?
206 bones
Two Types of Bones
Compact bone
Spongy bone
strongest form of bone tissue
