QuestionChoice
This is not the correct answer. The vagina is a muscular tube which is composed of four histological layers, where the outermost epithelial layer is the stratified squamous epithelium. However, the epithelium is not keratinized as stated in this option.

b
Stratified squamous keratinised epithelium
QuestionChoice
This is not the correct answer. Simple cuboidal epithelium is commonly found in glandular secreting tissue and kidney tubules. On the other hand, the vagina is a muscular tube which is composed of four histological layers, where the outermost epithelial layer is the stratified squamous non-keratinised epithelium. This layer provides protection and is lubricated by cervical mucus.

d
Simple cuboidal epithelium
QuestionChoice
This is not the correct answer. Simple columnar epithelium can be found in the endocervical canal (endocervix). On the other hand, the vagina is a muscular tube which is composed of four histological layers, where the outermost epithelial layer is the stratified squamous non-keratinised epithelium. This layer provides protection and is lubricated by cervical mucus.

c
Simple columnar epithelium
QuestionChoice
This is the correct answer. The vagina is a muscular tube which is composed of four histological layers, where the outermost epithelial layer is the stratified squamous non-keratinised epithelium. This layer provides protection and is lubricated by cervical mucus. The ectocervix, which is the distal portion of the cervix that projects into the vagina, is also lined by this type of epithelium.

a
Stratified squamous non-keratinised epithelium
QuestionChoice
This is not the correct answer. This describes the transformation zone between the ectocervix and endocervix, which is the usual site at risk of human papillomavirus high-risk subtypes (16 and 18) infection and cervical carcinoma. On the other hand, the vagina is a muscular tube which is composed of four histological layers, where the outermost epithelial layer is the stratified squamous non-keratinised epithelium. This layer provides protection and is lubricated by cervical mucus.
