Larynx intrinsic muscle tendon. সহজ বাংলা: মাংসপেশি/টেনডনে টান।" data-rx-term="strain" data-rx-definition="A strain is injury to a muscle or tendon. সহজ বাংলা: মাংসপেশি/টেনডনে টান।">strain is a condition that occurs when the small muscles inside the voice box (larynx) are overstretched or injured. These muscles control voice production, breathing, and help protect the airway during swallowing. When these muscles are strained, you may experience discomfort, voice changes, and difficulty breathing or swallowing.
Anatomy of the Larynx Intrinsic Muscles
Understanding the structure and function of the intrinsic muscles of the larynx is key to comprehending the impact of a tendon. সহজ বাংলা: মাংসপেশি/টেনডনে টান।" data-rx-term="strain" data-rx-definition="A strain is injury to a muscle or tendon. সহজ বাংলা: মাংসপেশি/টেনডনে টান।">strain. Here is a breakdown of the anatomical details:
Structure & Location
-
Location: The larynx, or voice box, is located in the front of the neck, just below the pharynx (throat). It sits atop the trachea (windpipe).
-
Components: The larynx consists of cartilage, muscles, ligaments, and membranes. The intrinsic muscles are housed within the larynx and are essential for adjusting the tension and position of the vocal cords.
Origin and Insertion
-
Origin: The intrinsic muscles originate from various parts of the laryngeal cartilages (thyroid, cricoid, and arytenoid cartilages).
-
Insertion: They attach to different cartilages within the larynx, allowing them to change the shape and tension of the vocal cords.
-
Examples:
-
Thyroarytenoid muscle: Originates from the thyroid cartilage and inserts into the arytenoid cartilage.
-
Cricothyroid muscle: Originates from the cricoid cartilage and inserts into the thyroid cartilage.
-
Blood Supply
-
Arterial Supply: The larynx receives blood from small branches of the superior thyroid artery and inferior thyroid artery. These vessels provide the oxygen and nutrients needed for muscle function.
-
Venous Drainage: Blood is drained via the superior and inferior laryngeal veins.
Nerve Supply
-
Primary Nerve Supply: The recurrent laryngeal nerve (a branch of the vagus nerve) and the superior laryngeal nerve are the main nerves that control the laryngeal muscles.
-
Function: These nerves provide motor control for the muscles that open, close, and tense the vocal cords.
Key Functions of the Larynx Intrinsic Muscles
-
Voice Production: Adjusting the tension of the vocal cords to produce different pitches.
-
Breathing Regulation: Opening and closing the airway to control airflow during breathing.
-
Protective Reflexes: Preventing food and liquid from entering the airway during swallowing.
-
Cough Reflex: Helping to clear the airway by initiating a cough.
-
Pitch and Volume Control: Modulating vocal intensity and tone.
-
Fine-Tuning of Sound: Allowing subtle adjustments for clear speech and singing.

-
Acute vs. Chronic:
-

-
Chronic strains result from repeated misuse or prolonged stress on the muscles.
