Which muscle shortens and thickens the vocal cords to lower pitch?
Cricothyroid
Thyroarytenoid/vocalis muscle
Posterior cricoarytenoid
Omohyoid
Which muscle depresses the hyoid or elevates the larynx to close the airway?
Thyroarytenoid
Thyrohyoid
Cricothyroid
Lateral cricoarytenoid
Which action is performed by the thyrohyoid muscle?
Depresses, retracts, and steadies hyoid
Elevates mandible
Depresses hyoid; elevates larynx
Retracts tongue
Which muscle is shown to have both an upper and lower head in the provided anatomical diagram?
Lateral pterygoid muscle
Masseter muscle
Temporalis muscle
Medial pterygoid muscle
(DoK Level 3) A patient presents with loss of sensation in the lower lip and chin, as well as dental pain in the lower jaw. Which branch of the maxillary artery is most likely compromised, and what other structure might be affected?
Inferior Alveolar Artery; mandible
Deep Temporal Arteries; temporalis muscle
Buccal Artery; cheek mucosa
Middle Meningeal Artery; dura mater
What is another name for the auricular branch of the vagus nerve?
Alderman’s nerve or Arnold’s nerve
Jacobson’s nerve
Bell’s nerve
Trochlear nerve
Which muscle is related to the right kidney at the 12th rib only?
Diaphragm
Psoas Major
Quadratus Lumborum
Rectus Abdominis
Which nerves cross the abdominal muscles as neurovascular structures?
Subcostal Nerve, Iliohypogastric Nerve, Ilioinguinal Nerve
Femoral Nerve, Sciatic Nerve, Tibial Nerve
Radial Nerve, Ulnar Nerve, Median Nerve
Phrenic Nerve, Vagus Nerve, Accessory Nerve
The palatoglossus muscle of the tongue is supplied by which nerve?
Vagus nerve
Hypoglossal nerve
Facial nerve
Accessory nerve
Killian’s dehiscence is outpouching of
Oropharynx
Nasopharynx
Laryngopharynx
Trachea
Killian’s dehiscence is a common site for the development of a pharyngeal diverticulum because:
It is a weak area between the thyropharyngeus and cricopharyngeus muscles.
It is protected by the larynx.
It is located in the retrosternal space.
It is the strongest part of the pharyngeal wall.
Which of the following is a feature of unilateral recurrent laryngeal injury?
Hoarseness of voice
Respiratory stroke
Hot potato voice
Laryngeal spasm
What is the effect of bilateral recurrent laryngeal nerve injury in its acute phase?
Hoarseness
Stridor, respiratory distress
Aphonia
Minimal effects
If a patient presents with aphonia, which of the following nerve injuries could be responsible?
Unilateral superior laryngeal nerve injury
Bilateral recurrent laryngeal nerve injury (chronic)
Unilateral vagus nerve injury
Unilateral recurrent laryngeal nerve injury
Which condition is often indicated by a high USG (concentrated urine)?
Overhydration
Dehydration or presence of glucose/protein
Renal tubular necrosis
Diabetes insipidus
A low USG value (near 1.010 or less) in a first morning sample strongly suggests what?
Normal kidney function
Defect in kidney's concentrating ability
High blood pressure
Excessive protein intake
What is the main purpose of evaluating deep tendon reflexes in a neurological examination?
To measure muscle strength
To assess neurological diseases affecting nerves and pathways
To determine blood flow in muscles
To check bone density
