Why is the laryngeal nerve 15 feet long in giraffes?
The laryngeal nerve in giraffes is 15 feet long because it takes a longer route in the body, looping around the aorta and the subclavian artery. This is a result of the nerve's development in evolutionary history, where it was shorter in smaller ancestors and gradually lengthened as the giraffe's neck elongated over time.
What is another name for laryngeal pharynx?
Another name for laryngeal pharynx is the voice box.
What is an example of an latent virus?
an example of a latent virus is a host cell
What is the scientific term for Adam's apple?
The scientific term for Adam's apple is the laryngeal prominence. It is a noticeable protrusion in the front of the neck that is more prominent in males due to the larger size of the larynx.
What is the common name for the laryngeal prominence?
The common name for the laryngeal prominence is the Adam's apple. It is more prominent in males due to the effects of testosterone during puberty, which causes the enlargement of the thyroid cartilage.
Which nerve is most commonly damaged during thyroidectomy External laryngeal or recurrent laryngeal nerve?
The recurrent laryngeal nerve is the most commonly damaged nerve during throidectomy.
Which laryngeal nerve accompanies inferior thyroid artery?
recurrent laryngeal nerve
What is the nerve supply to the larynx?
The larynx receives its nerve supply from the vagus nerve (cranial nerve X). Specifically, the recurrent laryngeal nerve innervates the intrinsic muscles of the larynx involved in phonation, while the external branch of the superior laryngeal nerve supplies the cricothyroid muscle.
What is the major risk in undergoing a parathyroidectomy?
The major risk of parathyroidectomy is injury to the recurrent laryngeal nerve (a nerve that lies very near the parathyroid glands and serves the larynx or voice box).
What causes recurrent laryngeal nerve palsy What can you do to help it recover?
The nerve is best known for its importance in thyroid surgery, as it runs immediately posterior to this gland. If it is damaged during surgery, the patient will have a hoarse voice. Nerve damage can be assessed by laryngoscopy, during which a stroboscopic light confirms the absence of movement in the affected side of the vocal cords. Similar problems may also be due to invasion of the nerve by a tumor or after trauma to the neck. A common scenario is paralysis of the left vocal cord due to malignant tumour in the mediastinum affecting the left branch of the recurrent laryngeal nerve. The left cord returns to midline where it stays. If the damage is unilateral, the patient may present with voice changes including hoarseness. Bilateral nerve damage can result in breathing difficulties and aphonia, the inability to speak. The right recurrent laryngeal nerve is more susceptible to damage during thyroid surgery due to its relatively medial location.
What are some complications that could occur from a mediastinoscopy?
Hemorrhage; pneumothorax; recurrent laryngeal nerve injury, causing hoarseness; infection; tumor implantation in the wound; phrenic nerve injury; esophageal injury; chylothorax; air embolism; transient hemiparesis.
What nerve requires careful dissection during thyroid surgery?
The Laryngeal Nerve.
What does it mean when the cancer is pressing on the nerve in a lung cancer patent?
Cancer masses can grow to such an extent or be located in an area that makes them particularly likely to press against and impinge upon a nerve. The implications for nerve impingement vary according to the exact nerve the mass is pressing against. For example, a lung cancer might compress the left recurrent laryngeal nerve and cause hoarseness.
What are side effects after a thyroidectomy regarding a persons mental state?
Hoarseness or voice loss may develop if the recurrent laryngeal nerve was injured or destroyed during the operation. This is more apt to occur in patients who have large goiters or cancerous tumors.
What is the nerve supply of trachea?
The trachea is primarily innervated by the vagus nerve (cranial nerve X), which provides parasympathetic fibers that regulate secretions and bronchoconstriction. Additionally, sympathetic innervation comes from the sympathetic trunk, which helps to modulate blood flow and bronchial dilation. Sensory innervation is primarily through the recurrent laryngeal nerve, a branch of the vagus, which conveys sensation from the mucosal lining of the trachea.
What happens if the laryngeal nerve is injured during a parathyroidectomy?
If this nerve is injured, the voice may become hoarse or weak.
What are the Causes of adult laryngeal nerve palsy?
multiple sclerosis- could be a sympton of
