The carotid artery and external jugular vein are not compressed by the muscles in the neck because they are located deep within the neck and are protected by layers of tissue and structures such as the sternocleidomastoid muscle. Additionally, the carotid artery is a vital blood vessel that supplies blood to the brain, so compressing it could lead to serious consequences such as stroke. The external jugular vein is a low-pressure vein that can collapse easily without causing harm, so it is not as critical to protect from compression. **
