Hist Lab 3 - Cartilage

most abundant tissue in the body

Chondrocytes in lacunae of Hyaline Cartilage - fed by diffusion, synthesize and maintain matrix, round nucleus, glycogen and lipid in the cytoplasm

perichondrium - Dense CT wrapping, contains collagen type 1 fiber, fibroblasts, and blood vessels

Simple squamous

Perichondrium

An isogenous group of chondrocytes (lat. "equal origin") is a cluster of up to eight chondrocytes found in hyaline and elastic cartilage.

newly trapped chondrocytes developing from cells in the perichondrium

stratified squamous epithelium, NONkeratinized

pseudostratified epithelium (with cilia)

loose connective tissue - contains flat fibroblasts (black squished dots)

dense regular connective tissue

Chondrocytes in hyaline cartilage

pseudostratified epithelium, cilia

dense irregular connective tissue

Articular cartilage, is the hyaline cartilage at the ends of bones in
joints. It lacks a perichondrium, receiving oxygen and nutrients
from the synovial fluid of the joint capsule.
