Animal Tissue and Anatomy

The pyloric sphincter, or valve, is a strong ring of smooth muscle, at the end of the pyloric canal, and lets food pass from the stomach, to the duodenum. It receives sympathetic innervation from celiac ganglion.

Back of the tongue helps detect bitter taste as in the case of tasting bitter gourd.

The front part of the tongue detects sweet and salty taste of any food item.

The thin membrane at the end of the auditory canal is called tympanic membrane.

In the inner ear, the pressure variations are turned into electrical signals by cochlea. These electrical signals are sent to the brain via auditory nerve and the brain interprets them as sound.

The epiglottis is flap of cartilage located in the throat behind the tongue and in front of the larynx. The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs. After swallowing the epiglottis returns to its original upright position.

The liver is the largest gland of the human body, with a weight of about 3 to 3½ lb (1.4 to 1.6 kg). It is an accessory digestive organ.It secretes bile, a greenish, bitter juice which breaks up the fatty part of the food into tiny drops. Bile from the liver is collected in the gall-bladder from which it flows into the intestine.

The windpipe is also known as trachea.It joins the the the upper respiratory tract to the lungs. If you gently touch the front of your throat you can feel the trachea. The bottom of the trachea splits into two branches called bronchi. One enters the right lung and one goes to the left lung.

Vocal cords are structures in the larynx which are designed to vibrate when air passes by, producing sound. These structures allow people to speak, and they also help to protect the lungs from accidental inhalation of food, saliva, and mucus. 

The external female genitals are collectively referred to as vulva.

We have five sense organs, namely: eyes, ears, skin, nose, tongue.

Ear ossicles transfer vibrations from the external ear to the inner ear.

Our sense of taste comes from the taste buds on our tongue. The tongue is able to taste four separate flavors: salty, sweet, sour and bitter.

Skin can feel hot,cold and soft things.

Tongue possesses gustatory receptors.
