W14 Tissues

Question 1

What are the 4 types of connective tissue?

What do they each consist of?

Answer 1

Proper:
Loose, Dense (regular + irregular)

Bone:
Spongy, compact

Cartilage:
Hyaline, Fibrocartilage, Elastic

Blood:
Plasma, RBC’s, WBC’S, platelets

Question 2

What 3 components makes up connective tissue?

Answer 2

Protein fibres, cells, ground substance

Question 3

Which 2 components makes up the ECM?

Answer 3

Protein fibres + ground substance

Question 4

What’s special about connective tissue cells?

Answer 4

They create the ECM

Question 5

What are the 3 types of cells making up cartilage, bone and protein fibres?

Answer 5

Chondrocytes, osteocytes, fibrocytes

Question 6

Name the 3 tissue components of loose connective tissue

Answer 6

Adipose tissue, Retiuclar tissue, Areolar tissue

Question 7

What are the 2 components and 2 subcomponents of Dense connective tissue
What characterises them (histologically)
Give examples of where to find each

Answer 7

Regular: protein fibres run in one direction
slightly yellow
Elastic = found in vocal folds,
Collagenous = tendons,ligaments

Irregular: mesh of protein fibres
Elastic = arteries
Collagenous = dermis

Question 8

Categorise the 3 types of muscle cell and describe their main characteristics (histologically)

Answer 8

Skeletal:
Multiple nuclei
Celar striations, no junctions between cells

Cardiac:
Striations, cell branches
Shorter than skeletal cells

Smooth:
Cells tapered on each side

Question 9

What 2 parts does nervous tissue consist of?

and what are they?

Answer 9

Neurones: nerve cells
Glia: supporting cells

Question 10

What are the 3 types of neurone?

What functions do they have/where can they be found?

Answer 10

Multipolar: Multiple dendrites + 1 axon
CNS + skeletal muscle

Bipolar: 1 dendrite + 1 axon
Special somatic NS (special senses like hearing, vision)

Pseudpunipolar:
General Somatic Afferent (Sensory Peripheral NS)

Question 11

Define these three types of epithelial tissue:
Endothelium
Endocardium
Mesothelium

Answer 11

Endothelium = the epithelial lining of the blood and lymphatic vessels.
Endocardium = the epithelial lining of ventricles and atria of the heart.
Mesothelium = the epithelium that lines the walls and covers the contents of the closed cavities of the body
