Histology - Connective tissues and other

Match the tissue name with the appropriate lettered structure

• A

• Epithelium,

• B

• dense connective tissue

• C

• loose connective tissue

Answer explanation

remember: the denser the tissue, the less cells you see.

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.

Which one of these 2 dense connective tissue is regular?

• A

• B

• none

Answer explanation

A has all its collagen bundles are parallel to one another so it is a regular dense CT

Which one of these 2 dense connective tissue is IRregular?

• A

• B

• none

Answer explanation

its collagen bundles are some time parallel to one another and sometime at an angle. When cut, this angled fiber will show as oblong structures. This is typical of a irregular dense CT

What type of connective tissue is A?

• Loose CT

• Dense regular CT

• Dense irregular CT

• cardiac muscle

What type of connective tissue is B?

• Loose CT

• Dense regular CT

• Dense irregular CT

• cardiac muscle

What type of connective tissue is C?

• Loose CT

• Dense regular CT

• Dense irregular CT

• cardiac muscle

This connective tissue has two types of fibers. The red arrow points to collagen fibers and the green arrow point to a very springy type of fiber. What connective tissue is this?

• Loose CT

• Dense irregular

• Loose elastic CT

• Dense irregular

Answer explanation

there is many cells in there so it is a loose CT.

The "springy" green fibers are elastin fibers. They give this elastic (springy) property to this tissue. It is there a loose CT.

This connective tissue is dense regular

• True

• False

Answer explanation

False. The collagen fibers are not parallel to one another.

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
