choose all that are the skeletal attachments of the sternocleidomastoid muscle.

scapula

zygomatic arch

manubrium and clavicle

mastoid process

Explanation:

Identify the muscle and its anatomical name

Using the Sternocleidomastoid Muscle knowledge point, we break down the name of the muscle to identify its attachments:

• Sterno- refers to the sternum (specifically the manubrium).
• Cleido- refers to the clavicle.
• Mastoid refers to the mastoid process of the temporal bone.

Evaluate the given options

Using the Skeletal Attachments knowledge point:

• Scapula: The sternocleidomastoid does not attach to the shoulder blade.
• Zygomatic arch: The sternocleidomastoid does not attach to the cheekbone.
• Manubrium and clavicle: These represent the inferior origins of the muscle.
• Mastoid process: This represents the superior insertion of the muscle.

Answer:

• Scapula
• Zygomatic arch
• Manubrium and clavicle (Correct answer)
• Mastoid process (Correct answer)
