Question

Which of the following tissues is avascular?
A. Tendon
B. Skeletal muscle
C. Stratified Squamous epithelium
D. Adipose tissue

Answer 1

Hint: The avascular tissue (among the given options) comprises squamous or flattened epithelial cells. These cells are arranged in layers upon the basal membrane. Only one layer of these cells is attached to the basement membrane but the other layers are in contact with other epithelial cells that help to maintain structural integrity.

Step by step answer:The stratified squamous epithelium is avascular, which means it lacks blood vessels in their structure. The tissue that is attached to the basal layer contains cuboidal and columnar epithelial cells also. The nuclei of these cells are oval and cell division takes place by mitosis process to form new daughter cells.
The newly formed cells move outward but in the middle layers, the cells become polyhedral in shape and have rounded nuclei and are called intermediate layers. The cells of superficial layers become flat and have transversely elongated nuclei, called squamous layers. There are two types of stratified squamous epithelial cells present in the body – keratinized and non-keratinized.
Hence, the correct answer is option C, i.e., Stratified squamous epithelium

Note: Tendon, skeletal muscle, and adipose tissue are the connective tissues that have enough blood supply through the blood vessels. It means these tissues are vascular.
