Hypobranchial Muscles Of A Cat - Quiz


This quiz is designed to help students recognize the hypobranchial muscles of a cat. It will also help them learn the origins, insertions, and actions of these muscles.


Questions and Answers
  • 1. 

    In the picture above, identify "D"- muscle and it's action.

    • A.

      Sternomastoid: is involved in flexion and turning of the head

    • B.

      Sternohyoid: retracts the larynx

    • C.

      Cleidomastoid: turns the head and moves the clavicle anteriorly

    • D.

      Sternohyoid: retracts the hyoid

    Correct Answer
    D. Sternohyoid: retracts the hyoid
    Explanation
    The correct answer is Sternohyoid: retracts the hyoid. The Sternohyoid muscle is responsible for pulling the hyoid bone downwards and backwards, helping to retract it. This action is important for swallowing and speaking.

    Rate this question:

  • 2. 

    What is the origin and insertion of the muscle labeled "A"?

    • A.

      Origin: First costal cartilage; Insertion: Thyroid cartilage of the larynx

    • B.

      Origin: Lateral portion of the thyroid cartilage of the larynx; Insertion: Hyoid bone

    • C.

      Origin: Clavicle; Insertion: Mastoid process of the temporal bone

    • D.

      Origin: Stylohyal; Insertion: Body of the hyoid

    Correct Answer
    B. Origin: Lateral portion of the thyroid cartilage of the larynx; Insertion: Hyoid bone
  • 3. 

    The muscle that originates at the first costal cartilage, inserts at the thyroid cartilage of the larynx, and works in retracting the larynx is the ____________

    Correct Answer
    sternothyroid
    Explanation
    The sternothyroid muscle originates at the first costal cartilage and inserts at the thyroid cartilage of the larynx. Its main function is to retract the larynx. Therefore, the sternothyroid muscle is the correct answer to the question.

    Rate this question:

  • 4. 

    Identify the muscle labeled "B".  This muscle lies posterior to the __________.

    • A.

      ID: Geniohyoid; hyoglossus muscle

    • B.

      ID: Sternothyroid; digastric muscle

    • C.

      ID: Sternohyoid; thyrohyoid muscle

    • D.

      ID: Geniohyoid: mylohyoid muscle

    Correct Answer
    D. ID: Geniohyoid: mylohyoid muscle
    Explanation
    The muscle labeled "B" is the geniohyoid muscle. It lies posterior to the mylohyoid muscle.

    Rate this question:

  • 5. 

    What is the action of the geniohyoid muscle?

    • A.

      Protracts the hyoid

    • B.

      Retracts and depresses the tongue

    • C.

      Elevates the floor of the mouth

    • D.

      Retracts the larynx

    Correct Answer
    A. Protracts the hyoid
    Explanation
    The geniohyoid muscle is responsible for protracting the hyoid bone. Protraction refers to the movement of bringing a body part forward or in an anterior direction. In this case, the geniohyoid muscle helps to move the hyoid bone forward, which can be important for actions such as swallowing and speaking.

    Rate this question:

  • 6. 

    This muscle inserts in the tongue and draws the tip of the tongue backward and the root of the tongue forward:

    • A.

      Hypoglossus muscle

    • B.

      Genioglossus muscle

    • C.

      Geniohyoid muscle

    • D.

      Mylohyoid muscle

    Correct Answer
    B. Genioglossus muscle
    Explanation
    The genioglossus muscle is responsible for inserting in the tongue and drawing the tip of the tongue backward and the root of the tongue forward. This muscle plays a crucial role in controlling tongue movements, such as protrusion and retraction. By contracting, it helps to shape the tongue and facilitate actions like swallowing, speaking, and chewing.

    Rate this question:

  • 7. 

    The muscle that lies lateral to the geniohyoid and retracts and depresses the tongue is the ___________ muscle.

    Correct Answer
    hyoglossus
    Explanation
    The muscle that lies lateral to the geniohyoid and retracts and depresses the tongue is the hyoglossus muscle.

    Rate this question:

  • 8. 

    The styloglossus:

    • A.

      Inserts in the tongue and retracts and depresses the tongue.

    • B.

      Inserts in the tongue and draws the tip of the tongue backward and the root forward.

    • C.

      Inserts in the tongue and retracts and elevates the tongue.

    • D.

      Inserts in the tongue and protracts the hyoid.

    Correct Answer
    C. Inserts in the tongue and retracts and elevates the tongue.
    Explanation
    The styloglossus muscle is responsible for inserting in the tongue and retracting and elevating the tongue. This means that it helps in pulling the tongue back and also raising it upwards. The other options mentioned in the question, such as drawing the tip of the tongue backward and the root forward or protracting the hyoid, are not the functions of the styloglossus muscle.

    Rate this question:

  • 9. 

    Identify the muscle labeled "D".

    • A.

      Styloglossus

    • B.

      Geniohyoid

    • C.

      Sternohyoid

    • D.

      Sternothyroid

    Correct Answer
    D. Sternothyroid
    Explanation
    The muscle labeled "D" is the Sternothyroid muscle.

    Rate this question:

  • 10. 

    Check all of the muscles that help move the tongue.

    • A.

      Mylohyoid

    • B.

      Genioglossus

    • C.

      Sternohyoid

    • D.

      Styloglossus

    Correct Answer(s)
    B. Genioglossus
    D. Styloglossus
    Explanation
    The correct answer is Genioglossus and Styloglossus. These muscles are both located in the tongue and play a role in its movement. The Genioglossus muscle helps to protrude and retract the tongue, while the Styloglossus muscle helps to elevate and retract the tongue. The other two options, Mylohyoid and Sternohyoid, are not directly involved in tongue movement.
