Question

What is wry neck?? which muscle and nerve does it affect?​

Answer 1

Wry neck, or cervical dystonia, is a condition characterized by involuntary contractions of the neck muscles, causing the head to twist to one side. It affects the sternocleidomastoid and trapezius muscles, which are controlled by the accessory nerve.

Step-by-step explanation:

Wry neck, also known as cervical dystonia or spasmodic torticollis, is a condition characterized by involuntary contractions of the neck muscles, causing the head to twist to one side.

The muscles affected by wry neck are the sternocleidomastoid and trapezius muscles. The accessory nerve, also called the spinal accessory nerve, innervates these muscles and controls their movement.

Answer 2

Wry neck, also known as torticollis, is a condition characterized by the twisting or tilting of the head to one side.

This condition can be congenital (present at birth) or acquired (developed later in life). There are several potential causes of wry neck, including muscle spasms, injury, inflammation, or abnormalities in the cervical spine.

The muscles most commonly affected in wry neck are the sternocleidomastoid muscles, which are located on either side of the neck. These muscles play a significant role in head movement and neck rotation. When one sternocleidomastoid muscle contracts or becomes shortened, it causes the head to tilt or rotate in the opposite direction.

The nerves associated with wry neck are primarily the spinal accessory nerve (cranial nerve XI) and the cervical nerves. The spinal accessory nerve controls the sternocleidomastoid and trapezius muscles.
