; Sternocleidomastoid muscle - this branchiomeric muscle flexes the head (prayer muscles) when both left and right members contract. The neck twists or rotates when only one contracts. Its antagonist is the splenius capitis, a somatic muscle (which extends the head). Both these muscles act as 1st class levers.
Practiced by lying on the back, lifting legs over the head, touching the floor behind your head.
The splenius captious is a muscle in the back of the neck. It connects the back of the skull to the upper body. The muscle is used when one shakes their head.

Then you probably strained them.
Isotonic exercise (or muscle contraction) is when the muscle contracts and shortens giving movement (ie a bicep curl, lifting and lowering weight) Nearly all the training you do is Isotonic the opposite is Isometric, where the muscle contracts but des not shorten, giving no movement. Eg, Weightlifting, Lifting the weight up and down is isotonic Holding the weight still above the head is isometric
The muscle responsible for elevating and retracting the lower jaw is the temporalis muscle. This fan-shaped muscle is located on the side of the head and plays a key role in the process of mastication (chewing). When it contracts, it not only raises the mandible but also pulls it backward, contributing to the retraction movement.
Most likley... muscle tension.
The splenius capitis muscle allows you to look up. This muscle is located at the back of the neck and helps to extend and rotate the head.
