Together, these muscles facilitate plantarflexion of the ankle, allowing your toes to point downward.
Does the sternocleidomastoid rotate to same side?
The sternocleidomastoid muscle primarily rotates the head to the opposite side. When one side of the sternocleidomastoid contracts, it causes rotation of the head towards the opposite side while also tilting it to the same side. However, if both sides contract together, they flex the neck forward. Thus, the muscle does not rotate the head to the same side; that action is performed by other muscles.
