Histology: Connective tissues Classification (subtype: connective tissue proper) Flashcards

1
Q

Describe the common Connective Tissue structural characteristics

A

Mainly supports and connects tissue

cells are far a part, separated by an extarcellular matrix (ex. outside a bone)
- extraceullular material, gives CT subtypes their identifying characteristics

variable vascularity (some has blood vessels and some dont)

Q

Describe how the cells of connective tissues are named, giving examples

A

blast, cyte and clast

blast: creates a matrix e.g osteoblast, chondroblast, fibroblast
Cyte: maintains matrix e.g osteocyte, chondrocyte, fibrocyte
Clast: breakdown matrix e.g osteoclast (no cartiladge, or CT proper)
- only found in bone (very hard matrix)

Q

Fibres (proteins)

A

matrix composition of the connective tissue
- collagen fibres (for strength)
- elastic fibres (containing elastin - allow stretch and recoil) Analogy: like a rubber band if let go = back to original shape
- reticular fibres (forming network - e.g CT part of basement membrane)

Q

Collagen fibres

A

Fibres (a part of the matrix composition for CT)
used for strength

Fibres found in areolar, dense regular, dense irregular, bones and cartilage matrix’s

Q

Ground substance

Where is it found? What is the purpose of a ground substance? What is it composed of and give examples

A

A part of matrix composition of connective tissue
unstructure material surrounding extracellular fibres and cells

Composed of: water and large organic molecules = large proteoglycans (contain proteins and polysaccarides

e.g hyaluronic acid, chondroitin sulphate

Q

How is connective tissue classified? List the subtypes of connective tissue

A

Classification mainly by matrix composition (recall: fibres(proteins) and ground substance)

Subtypes of Connective tissue:
1. connective tissue proper - actually connects! (loose CT (subtypes: areolar CT and adipose) and dense CT ( subtypes: dense regular and dense irregular))
2. cartilage
3. Bone
4. blood

Q

Characteristics of Connective Tissue Proper

Name each subtype and explain their characteristics

A

Cells = fibroblast (creates matrix)/fibrocytes(maintains matrix) except adipose tissue (adiposecytes)

Types of connective tissue proper
1.Loose CT (areolar and adipose)
* Areolar CT (highly vascular = provide nutrients)
* Matrix: loosely arranged collagen and elastic fibres,surrounded by ground substance, hyaluronic acid
* e.g lamina propria= special name to a CT part of mucous membrane
* Adipose (highly vascular)
* very little matrix
* cells large (adipocytes) - store triglygercides (tissue looks like chickenwire)

2.Dense CT (dense regular and dense irregular)
Many fibres (also known as fibrous CT)
little ground substance
poorly vascular
* Dense regular (fibrous CT = many fibres)
* collagen fibres running in same direction
* e.g tendons (muscle->bone join), ligaments (bone->bone)
* Dense irregular
* collagen fibres arranged irregularly ability to move around, provide flexibility
* e.g dermis of skin

Q

Loose Connective Tissue

A

Loose CT is a subtype of connective tissue proper

Two types of Loose CT: Areolar connective tissue and Adipose Tissue
Areolar CT (highly vascular = provide nutrients)
* loosely arranged collagen and elastic fibres surrounded by ground substance (hyraulonic acid)
* e.g lamina propria = special name to a CT part of mucous membrane

Adipose (highly vascular)
* very little matrix
* cells large (adipocytes) - store triglygercides (tissue looks like chickenwire)

Q

Lamina Propria

A

Type of areolar connective tissue

A special name of connective tissue thats a part of the mucous membrane

17
Q

Dense Connective tissue

Characteristics and subtypes

A

Dense CT is a subtype of connective tissue proper
Characteristics
Many fibres (also known as fibrous CT)
little ground substance
poorly vascular

Two subtypes dense regular and dense irregular
* Dense regular (fibrous CT = many fibres)
* collagen fibres running in same direction
* e.g tendons (muscle->bone join), ligaments (bone->bone)
* Dense irregular
* collagen fibres arranged irregularly ability to move around, provide flexibility
* e.g dermis of skin

18
Q

Areolar Connective Tissue

Characteristics and example

A

Subtype of Loose CT (Loose CT is a subtype of connective tissue proper)

Cells: Fibroblast/fibrocytes

highly vascular = provide nutrients

Matrix
Fibres: loosely arranged collagen and elastic fibres
ground substance (surrounding): hyraulonic acid

e.g lamina propria = special name to a CT part of mucous membrane (in simple organs)

Simple organ Membranes: mucous, serous, synovial and cutaneous

19
Q

Adipose Tissue

A

A type of Loose CT (Loose CT is a subtype of connective tissue proper)
highly vascular
* very little matrix
* cells: large ADIPOCYTES - store triglygercides (tissue looks like chickenwire)

20
Q

Dense regular

A

Subtype of Dense CT (Dense Ct is a subtype of connective tissue proper)
(fibrous CT = many fibres)
* collagen fibres running in same direction
* e.g tendons (muscle->bone join), ligaments (bone->bone)

21
Q

Dense irregular

A

Subtype of Dense CT (Dense CT is a subtype of connective tissue proper)
collagen fibres arranged irregularly ability to move around, provide flexibility
* e.g dermis of skin

Simple organ membranes: Cutaneous membrane (skin)
