Skeletal Cartilage
made of some variety of cartilage tissue which consists primarily of water.
has no nerves or blood vessels and is surrounded by dense irregular connective tissue.
Has a flexible matrix that can accommodate mitosis.
is when calcium salts deposited in the matrix and cause it to harden
3 types of cartilage contain the same basic components
-chondrocyte cells
-lacunae within an extracellular matrix
Hyaline Cartilage
provide support with flexibility and resilience.
Is abundant in skeletal cartilage
Is present in:
Articular- covers the ends of long bones
Costal- Connects the ribs to the sternum
Respiratory- makes up larynx, reinforces air passages
Nasal- supports the nose.
The only fibers in the matrix are fine collagen fibers.
Elastic Fibers
are much like Hyaline cartilage but they contain elastic fibers
Found in the external ear epiglottis.
highly compressible and have great tensile strength
Texture a perfect intermediate between hyaline and elastic cartilages.
Consist of roughly parallel rows of chondrocytes alternating with thick collagen fibers.
Found in menisci of the knee and in intervertebral discs.
Bones in the Human body
206 Axial Skeleton bones of the skull, vertebral column, and rib cage.
Appendicular Skeleton upper and lower limbs, girdles (hip bones and shoulder bones)
contains the blood vessels from which nutrients diffuse through the matrix to reach the cartilage cells.
Important Functions of the Bone and Cartilage
Support- forms the framework that supports the body and cradles soft organs.

Protection- Provides a protective case for the brain, spinal cord and vital organs.

Movement- provides levers for muscles.

Mineral storage- reservoir for minerals especially calcium and phosphates

Blood cells formation- hematopoiesis occurs within the marrow cavities of bones.
