Exercise 7: Supportive Tissues Flashcards
are richly supplied with blood vessels, nerves and lymphatic material.
Bone
This type of cartilage is abundant in the external ear, wall of the eustachian tube and epiglottis. This type of cartilage is found in larynx, epiglottis and external ear.
Elastic cartilage
the matrix is pervaded with heavy collagenous fibers forming bundles between which are scattered cartilage cells which lie in rows. found in intervertebral disc
Fibro- cartilage
are scattered and lodged in spaces termed lacunae. also known as cartilage cells
Chondrocytes
In the margin between two consecutive concentric lamellae are tiny spaces called
Lacunae
is soft and pliable, translucent and vascular forming most of the temporary skeleton of the embryo, providing a model in which most bones develop and playing an important role in their growth mechanism.
Cartilage
the whole area is permeated with body matrix which is characteristically divided into small and well defined layers
Lamellae
The matrix is semi-transparent and has opalescent bluish tint.
Hyaline cartilage
innermost layer lining parallel and inner to the endosteum.
Endosteal lamellae
The center of innermost lamellae
Haversian canal system
includes the cartilages and bones. They serve as attachment for muscles and connective tissues.
Supportive tissue
Types of cartilage
Hyaline cartilage
Elastic cartilage
Fibro- cartilage
is outer circumferential lamellae-forming the outermost layer, lying parallel to and beneath the periosteum.
Periosteal lamella
Type of cartilage considered as “skeletal cartilage”
Hyaline cartilage
The osteocytes and a system of tiny tubules called
Canaculi
