Animal Tissue and Anatomy

This is the correct option. Squamous epithelium is made of thin, flat, irregular-shaped cells which fit together like floor tiles to form a compact tissue.

This is the correct option. Stratified squamous epithelium is waterproof and highly resistant to mechanical injuries. This is found in the skin and covers the external dry surface of the skin.

This is the correct option as adipose tissue is abundant below the skin and between the internal organs.

This is the correct option. Squamous epithelium forms the delicate lining of mouth, nose, etc. and the covering of tongue and skin.

This is the correct option as this is a false statement. In columnar epithelium, the component cells are pillar-like, and not thin and flat.

The drum-like component of the tympanic membrane is known as pars tensa.

It is the long, cylindrical part of the dog glans, which is completely distinct from the bulbar part.

The renal plexus is made up of filaments from the celiac plexus, the aorticorenal ganglion, and the aortic plexus. It is also conjoined by the smallest splanchnic nerve.

Pudendal plexus is a complex structure accomodating fibers that innervate both male and female genital organs, the rectal ampoule and the anus. In males, the pudendal plexus controls the erection and ejaculation of the penis.

Cerebrospinal fluid (CSF) is a clear colourless body fluid produced in the choroid plexus of the brain. It acts as a cushion or buffer for the cortex providing a basic mechanical and immunological protection to the brain inside the skull and serves a vital function in cerebral autoregulation of cerebral blood flow.

The midbrain, also called the mesencephalon, is the smallest and the most anterior part of the brainstem with a tubular appearance. It is involved in functions such as vision, hearing, movement of the eyes and body motor function.

The epiglottis is a flap-like structure located at the entrance of the larynx (wind pipe). When you swallow, it closes over the larynx to prevent food or liquid from entering the respiratory tract. The glottis is the vocal cord opening, larynx is the voice box, and pharynx is the shared passage for both air and food - none of these prevent entry.

Brain is the part of nervous system. All body organs send messages through the nerves, and nerves send them to brain. Brain orders all our actions like walking, talking, crying, laughing, reading, loving people and memorising things. 

Nerves are the part of nervous system. Nerves act like electric wires in the human body as they spread all over the body and send messages to brain. If we touch a hot cup, the nerves in the skin send message to the brain and then brain orders the hand to withdraw itself from the cup.

Heart is mainly a muscle. The heart muscle has arteries and veins attached to it, and it basically pumps blood to circulate through the body.
