Connective Tissue

What type of tissue is this?

• Reticular

• Vascular

• Osseous

• Hyaline Cartilage

What is this connective tissue?

• Dense regular CT

• Muscle

• Dense irregular CT

• Loose elastic CT

Answer explanation

Muscles are NOT connective tissues

This one has very few cells as observed by the dark purple nuclei so it is dense.

the bundles of collagen are parallel to one another so it is regular.

Where are you likely to find dense regular connective tissue?

• tendons

• dermis

• bones

• blood

• spleen

Answer explanation

the parallel collagen fiber give the tendons their unidirectional strength

There are 3 types of cartilages in the body. Match the type of cartilage with the location you are most likely to find them.

• intervertebral disc

• hyaline cartilage

• pinnae of the ear

• elastic cartilage

• knee koint

• fibrocartilage

Answer explanation

Fibrocartilage has many collagen fibers, making it the strongest type of cartilage. It is found in intervertebral discs, ligaments, and the pubic symphysis.

Elastic cartilage is very springy and is found in the epiglottis, the external ear, and the larynx.

Hyaline cartilage is the most common. It is found lining the bones in articulations (shoulder, knee, hip, etc...)

What kind of tissue is this?

• hyaline cartilage

• white adipose tissue

• brown adipose tissue

• bone

Answer explanation

the homogenous purple tint of the matrix and the presence of vacuoles where the chondrocytes are house ate hallmarks of hyaline cartilages.

What kind of tissue is this?

• hyaline cartilage

• white adipose tissue

• brown adipose tissue

• bone

Answer explanation

the white appearance of the tissue, the presence of a one large vacuole full of fat (= the white features) and a nucleus squished on the side of the cell is a hallmark of white adipose tissue. They also lack extensive extra cellular matrix.

What kind of tissue is this?

• hyaline cartilage

• white adipose tissue

• brown adipose tissue

• bone

Answer explanation

this is actually not stained with H&E. The black smudges are osteocytes, the brown matrix is a mix of collagen fibers with hydroxyapatite. At the center, we have a Harvesian Canal through which blood vessels are found.

Which of the following is NOT a type of connective tissue?

• Bone
• Cartilage
• Skin
• Blood

Which is NOT one of the 3 components that make up connective tissue?

• Extracellular matrix 
• Fibers
• Cells
• Basement membrane 

Most connective tissue is well vascularized. What does that mean?

• Poor blood supply
• Good blood supply
