Explanation: The bony partition between the tympanic cavity (cavity of the middle ear) and the auditory capsule (internal ear) is perforated by a small…

• A. Pterygoid
• B. Hyoid apparatus
• C. Parasphenoid

Explanation: Frontoparietals are a pair of long, broad, flattened and membranous bones.

• A. Columnar
• B. Squamous
• C. Cuboidal
• D. Ciliated

Explanation: Stratum germinativum (also stratum basale or basal cell layer) is the layer of keratinocytes that lies at the base of the epidermis…

• A. No cell product of epithelial cell
• B. Epidermal cell only
• C. Endodermal cell
• D. Both (b) and (c)

Explanation: Basement membrane (basal lamina) is a thin sheet of fibrous proteins that underlies and supports the cells of an epithelium, separating…

• A. Cartilagin
• B. Ossein
• C. Chondrin
• D. None of these

Explanation: Chondrin is a protein present in the matrix of cartilage. It forms a constituent of a compound called chondrin sulphate.

• A. Yellow fibrous connective tissue
• B. Modified white fibrous tissue
• C. Areolar tissue
• D. Adipose tissue

Explanation: White fibrous tissue has two forms: cords and sheets. The white fibres run parallel to form cords, called tendons.

• A. Inelastic white fibrous tissue
• B. Modified white fibrous tissue
• C. Modified yellow elastic fibrous tissue
• D. None of the above

Explanation: Ligament occurs in the form of cords in a modified yellow elastic fibrous tissue and connects bone with a bone.

• A. Are arranged indiscriminately
• B. Make a definite layer
• C. Continue to divide and help in organ function
• D. None of the above

Explanation: The simple epithelium consists of a single layer of cells resting on a basement membrane. This makes it a definite layer.

• A. Epithelial cells
• B. Muscle cells
• C. Nerve cells
• D. Gland cells

Explanation: Nerve cells are highly excitable cells specialized for impulse conduction.

• A. Elastic cartilage
• B. Hyaline cartilage
• C. Calcified cartilage
• D. Fibrous cartilage

Explanation: Nasal septum consists of hyaline cartilage. It is bluishgreen and translucent in appearance.

• A. Striated muscle
• B. Areolar tissue
• C. Stratified epithelium
• D. Myelinated nerve fibres

Explanation: In areolar tissue, there is interercellular space, so the quantity of extracellular material is present in this tissue.

• A. Bones with bones
• B. Fat body with muscles
• C. Integument with muscles
• D. Bones with muscles.

Explanation: Areolar tissue is a loose connective tissue comprised of a semifluid ground substance containing several kinds of loosely arranged fibres.
