    What is number 8 pointing to? - ProProfs

    What is number 8 pointing to?

    Explanation
    The number 8 is pointing to the Biceps Brachii muscle.

    Rate this question:

  • 7. 

    What muscle is synergistic with spinodeltoid?

    Explanation
    The acromiodeltoid muscle is synergistic with the spinodeltoid muscle. Synergistic muscles work together to produce a coordinated movement. In this case, both the acromiodeltoid and spinodeltoid muscles are involved in shoulder abduction, which is the movement of lifting the arm away from the body. The acromiodeltoid muscle assists the spinodeltoid muscle in this action, helping to stabilize and support the shoulder joint during abduction.

    Rate this question:

  • 8. 

    Which one of these is not a head in triceps brachii?

    • Medial

    • Ventral

    • Lateral

    • Long

    Correct Answer
    A. Ventral
    Explanation
    The triceps brachii is a muscle located on the back of the upper arm. It is composed of three heads: the long head, the lateral head, and the medial head. The term "ventral" refers to the belly or front side of the body, which is the opposite of the location of the triceps brachii. Therefore, "ventral" is not a head in the triceps brachii muscle.

    What is number 4 pointing to?

    Correct Answer
  • 10. 

    What is the action of Pectoralis Minor?

    • Pulls the forelimb away from the midline.

    • Rotates humerus caudally.

    • Extends the forearm

    • Draws the forelimb towards the midline

    Correct Answer
    A. Draws the forelimb towards the midline
    Explanation
    The action of the Pectoralis Minor is to draw the forelimb towards the midline. This means that when the Pectoralis Minor muscle contracts, it pulls the forelimb closer to the midline of the body. This action is important for movements such as adduction of the arm, where the arm is brought closer to the body.

  • 11. 

    What muscle in Necturus is spinodeltoid homologous with?

    Correct Answer
    Dorsalis Scapulae
    Explanation
    The muscle spinodeltoid in Necturus is homologous with the muscle Dorsalis Scapulae. This means that these two muscles have a common evolutionary origin and share similar functions or structures.

    Rate this question:

  • 12. 

    What muscle in Necturus is clavobrachialis homologous with?

    Correct Answer
    procoracohumeralis
    Explanation
    The muscle clavobrachialis in Necturus is homologous with the muscle procoracohumeralis. This means that these two muscles have a common evolutionary origin and share similar functions or structures.

    Rate this question:

  • 13. 

    __________ inserts on the surface of the spinodeltoid muscle.

    • Acromiodeltoid

    • Supraspinatus

    • Teres Major

    • Subscapularis

    Correct Answer
    A. Acromiodeltoid
    Explanation
    The acromiodeltoid inserts on the surface of the spinodeltoid muscle.

    Rate this question:

  • 14. 

    Where does infraspinatus originate?

    • From the surface of the infraspinous fossa

    • Cranial border of the scapula

    • Acromion of the scapula

    • Spine of the scapula

    Correct Answer
    A. From the surface of the infraspinous fossa
    Explanation
    The infraspinatus muscle originates from the surface of the infraspinous fossa. This is a depression located on the dorsal aspect of the scapula. The muscle attaches to this specific surface of the scapula, allowing it to function in the movement and stabilization of the shoulder joint.

    Rate this question:

  • 15. 

    Brachialis is homologous with what muscle from Necturus?

    Correct Answer
    Humeroantebrachialis
    Explanation
    The Brachialis muscle in Necturus is homologous to the Humeroantebrachialis muscle. Homologous muscles are those that have a similar structure and function in different species, indicating a common evolutionary origin. In this case, both the Brachialis muscle in Necturus and the Humeroantebrachialis muscle in another species share similarities in their location and function, suggesting that they have evolved from a common ancestor.

  • 16. 

    Lattisimus Dorsi inserts at the ______ surface of humerus at the ________ end.

    • Medial and Distal

    • Lateral and Distal

    • Medial and Proximal

    • Lateral and Proximal

    Correct Answer
    A. Medial and Proximal
    Explanation
    The correct answer is "Medial and Proximal". The lattisimus dorsi muscle inserts at the medial surface of the humerus, which is the inner side of the bone, and at the proximal end, which is the end closer to the body. This means that the muscle attaches to the inner side of the upper arm bone, closer to the body.

    Rate this question:

  • 17. 

    What is the action of the latissimus dorsi?

    • Pulls scapula dorsally and caudally

    • Adduct and stabilize the scapula

    • Pulls forelimb dorsocaudally

    • None of the above

    Correct Answer
    A. Pulls forelimb dorsocaudally
    Explanation
    The action of the latissimus dorsi is to pull the forelimb dorsocaudally. This means that it helps in moving the forelimb towards the back of the body and in a downward direction. The latissimus dorsi muscle is located in the back and is responsible for various movements of the shoulder and arm.
