Animal Tissue and Anatomy

Yes, it is the correct answer. A pseudostratified columnar epithelium forms the linning of the respiratory tract and of the ducts in the male reproductive system.

Yes, Pacinian corpuscles are simple nerve endings covered with multilamellar, ovoid structures resembling small onions. These corpuscles respond to deep pressure.

Cumulus oophorus is found in ovaries.These are the cluster of cells that surround the oocyte.

The fundus of the urinary bladder is the base of the bladder formed by the posterior wall. The smooth muscle of bladder contracts to expel urine from the body. The trigone lies in the internal surface of fundus of bladder.

This sense organ helps us to feel things around us. It is the largest sense organ in our body as it covers our whole body.

Cystic duct connects gall bladder to the common hepatic duct that arises from the liver. Cystic and common hepatic ducts together form the common bile duct.

Hamartomas are a group of benign tumors that have relatively normal cellular differentiation but the architecture of the tissue is disorganised.

Macrophages present in the linings of spleen are called medullary sinusoids. 

It stores fat and forms shock absorbing cushion around kidneys and eyeballs.

The voice box or larynx is located at the upper end of the windpipe (trachea), just below the epiglottis. This positioning allows it to protect the airway during swallowing while producing sound. Options B, C, and D incorrectly place it at the lower end or on the sides.

The larynx (voice box) contains the vocal cords and is the primary organ that produces sound in humans. The windpipe (trachea) conducts air, the tongue helps shape speech but doesn't produce sound, and the pharynx is a passage for both air and food.

The vocal cords (also called vocal folds) are the primary vibrating structures that produce sound in humans. When air passes through the larynx, the vocal cords vibrate, creating sound waves. The pharynx and windpipe help transmit sound, while lungs provide air, but only the vocal cords actually vibrate to generate sound.

The outer ear (pinna) has a funnel-like shape that helps collect sound waves from the environment and direct them into the ear canal toward the eardrum.
