Not found on floor of posterior triangle of neckQuestion 14Select one:a.Scalenus posteriorb.Splenius capitisc.Sclaneus mediusd.Levator scapulae
Solution
The answer is b. Splenius Capitis.
Here's why:
The posterior triangle of the neck is an anatomical area in the neck. It's bordered by the Sternocleidomastoid muscle, the trapezius muscle, and the middle third of the clavicle.
The floor of the posterior triangle of the neck is formed by muscles including the Semispinalis Capitis, Splenius Capitis, Levator Scapulae, Scalenus Medius, and Scalenus Posterior.
a. Scalenus Posterior - This is one of the muscles that forms the floor of the posterior triangle of the neck.
c. Scalenus Medius - This is also one of the muscles that forms the floor of the posterior triangle of the neck.
d. Levator Scapulae - This muscle also forms the floor of the posterior triangle of the neck.
b. Splenius Capitis - This muscle does not form the floor of the posterior triangle of the neck. It is located in the back of the neck, attaching to the base of the skull, and is not part of the floor of the posterior triangle. Therefore, the answer is b. Splenius Capitis.
