Histology: Connective tissue Classification (subtype: Bone, Cartilage and Blood), Muscle Tissue and Nervous Tissue Flashcards
Characteristics of Bone
cell and matrix
A subtype of connective tissue
Cell: osteocytes (in luncae), osteoblast, osteoclast
Matrix:
- Fibres: collagen
- Ground substance: hydroxyapatite (inorganic Ca++ and phosphate salts), organic component (proteoglycans;recall: organic molecule = proteins and polysaccarides) and water
very vascular
Characteristics of Cartilage
cell, matrix and type of vascularity and example
A subtype of connective tissue
cell: chondroblast and chondroclast (in luncae= cavities in matrix)
Matrix
fibres (protein): collagen, elastin (proteins)
Ground Substance: chondroitin sulphate and hyaluronic acid and water
avascular - heals slowly (no blood vessles, and cartilage is very dense)
example) hyaline cartilage of trachea, ribs, ends of long bones
Hydroxyapatite
ground substance for bones
- Inorganic substance containing CA+ and phosphate salts
Luncae
cavities in the matrix
osteocyte cells of bones and chondrocytes cells of cartilage are located in the lunace
Blood
A part of connective tissue
Cells: red blood cells (no mature nuclei), white blood cells (nuclei)
Matrix (fluid): plasmas (contains proteins, ground substance, water)
hyaline cartilage of trachea, ribs, ends of long bones
examples of the cartilage
Muscle Tissue
3 subtypes of muscle?
Contractile
subtypes
1. Skeletal (striated) -> very long and thin, many nuclei/cell
2. Cardiac (striated)
3. Smooth (non-striated)
Nervous tissue
Cell types?
cell types: Neurons and glial cells
Neurons: conduct electrical pulses
glial cells: support and protect neurons
glial cells
A part of nervous tissue
support and protect neurons
neurons
A part of nervous tissue
conduction electrical impulses
Hyaline Cartilage of trachea, end of long bones and ribs are examples of
The cartilage
