Aqueous Humour and Vitreous Humour.

The highlighted structure from the diaphragm is the external structure called the IRIS. The iris is the pigmented part if the eye that allows a certain amount of light to enter the eye through the iris dilator muscles.When the iris dilator muscle cells are stimulated, the cells contract, widening the pupil and allowing more light to enter the eye. I hope this helps, thanks.

A person who is severely allergic to nuts eats a candy bar without knowing that it contains finely chopped peanuts. Soon after massive inflammation in her pharynx blocks the passage of air to her trachea and lungs. An emergency tracheostomy must be performed. Explain why knowledge of the surface anatomy of the neck will help you perform this procedure successfully

Answers

Answer: A tracheostomy or called a stoma

Explanation:A tracheostomy is commonly referred to as a stoma. A tracheostomy is a medical procedure that either gives temporary or permanent opening in the neck in order to place a tube into a person's windpipe. This allows air to enter the lungs when it is not able to enter other ways. A tracheostomy is performed for several reasons, all involving someone not able to take in air, done during an emergency, when the airway is blocked. This allows air to enter the lungs. Breathing is then done through the tube, bypassing the mouth, nose, and throat.  This is the name for the hole in the neck that the tube passes through.

Without understanding of surface anatomy of the neck you could cause someone to bleed-out. Risks specific to a tracheostomy Include:

damage to the thyroid gland in the neck

erosion of the trachea, which is rare

lung collapse

scar tissue in the trachea

Knowledge of the surface anatomy of the neck is essential for performing a tracheostomy successfully. The neck is a complex region containing a variety of important structures, including the trachea, larynx, major blood vessels, and nerves. Understanding the location of these structures helps to minimize the risk of complications during surgery.

Here are some of the key surface anatomy landmarks of the neck that are important for tracheostomy:

Thyroid cartilage: This is the largest cartilage in the larynx and is also known as the Adam's apple. It is located in the midline of the neck just below the hyoid bone.

Cricoid cartilage: This is the ring-shaped cartilage that sits below the thyroid cartilage. It is the only complete ring of cartilage in the trachea.

Sternal notch: This is the V-shaped notch located at the top of the sternum. It marks the midline of the neck.

Sternomastoid muscle: This is a large muscle that runs along the sides of the neck. It is used to rotate the head and neck.

During a tracheostomy, the surgeon will make a small incision in the neck between the second and third tracheal rings. This is the ideal location for the tracheostomy tube because it is below the cricothyroid membrane, which contains important blood vessels and nerves. It is also above the carina, where the trachea divides into the left and right bronchi.
