It's particularly prominent in thin males, sits atop the tracheal rings, and can be seen best when the patient tilts their head backwards. Deviation to one side or the other is usually associated with intra-thoracic pathology.
For example, air trapped in one pleural space known as a pneumothorax can generate enough pressure so that it collapses the lung on that side, causing mediastinal structures, along with the trachea, to be pushed towards the opposite chest.
This deviation may be visible on inspection and can be accentuated by gently placing your finger in the top of the thyroid cartilage and noting its position relative to the midline. The thyroid gland lies approximately cm below the thyroid cartilage, on either side of the tracheal rings, which may or may not be apparent on visual inspection. If you're unsure, give the patient a glass of water and have them swallow as you watch this region.
Thyroid tissue, along with all of the adjacent structures, will move up and down with swallowing. The normal thyroid is not visible, so it's not worth going through this swallowing exercise if you don't see anything on gross inspection. Palpation: The thyroid can be examined while you stand in front of or behind the patient.
Exam from behind the patient is described below:. Palpating Anterior Cervical Lymph Nodes. Anterior Cervical both superficial and deep : Nodes that lie both on top of and beneath the sternocleidomastoid muscles SCM on either side of the neck, from the angle of the jaw to the top of the clavicle.
This muscle allows the head to turn to the right and left. The right SCM turns the head to the left and vice versa. They can be easily identified by asking the patient to turn their head into your hand while you provide resistance. Drainage: The internal structures of the throat as well as part of the posterior pharynx, tonsils, and thyroid gland.

However, when a lymph node is greater than 1 centimeter in diameter, it is enlarged.
The cervical lymph nodes sit deep inside the neck. For this reason, most people without medical training are unable to feel them, even when they are swollen. However, a doctor may be able to feel one or more bumps beneath the skin when examining the neck region. In some cases, a person with swollen cervical lymph nodes may experience pain and swelling in the neck area.
Many conditions can cause swollen cervical lymph nodes. Each cause is usually accompanied by additional symptoms. Infection is one of the most common causes of swollen lymph nodes anywhere in the body.
When there is an infection somewhere in the body, the lymph nodes in that area fill with white blood cells. The white blood cells then start to destroy the pathogens responsible for the infection.
Lymph nodes that swell as a result of infection are usually painful when a person touches them. However, they also tend to return to their normal size once the infection clears.
Less commonly, swollen cervical lymph nodes may be a sign of cancer. Cancers that affect the lymph nodes are called lymphomas.
These cancers typically cause swelling of the lymph nodes in more than one area of the body. There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. Non-Hodgkin lymphoma may develop in lymph nodes anywhere in the body, whereas Hodgkin lymphoma tends to develop in the neck, chest, or armpits. A person who experiences any of these symptoms in addition to enlarged lymph nodes should see their doctor. Hodgkin lymphoma is highly treatable if a person receives a diagnosis and starts undergoing treatment in the early stages.
Non-Hodgkin lymphoma is less treatable , but this is because doctors may not be able to diagnose it until it has reached an advanced stage.
