What muscle elevates the first two ribs?
scalenes
What are The principle flexors of the neck?
sternocleidomastoid and three scalenes
Is the sternocledomastoid muscle superficial or deep?
It depends on what you are comparing it to. It is deep to the skin and platysma. And it is superficial to the scalenes.
What is antagonist muscle to scalene?
Sternocleidomastoid and the Scalenes are Synergists, which mean that they work together to provide the same movements (flexion, rotation and lateral flexion of the head and neck)An Antagonist is a muscle that does the opposite movements. In this case, Antagonists of the Scalenes would be your posterior neck muscles, such as:Upper TrapeziusSplenius CapitusSplenius CervicisSemispinalis Capitis, etc
How would massage help torticollis?
Torticollis or "wry neck" is spasm of the sternocleidomastoid. You would massage the SCM along with the scalenes, trapezius, and splenius muscles.
What are the muscles involved when you take a deep breath?
The muscles of assisted inhalation are the external intercostal muscles, pectoral minor, and scalenes. The main muscle of respiration is the diaphragm.
What are the actions from the constructions in respiratory muscles?
Muscles of inspiration include: diaphragm, scalenes, pectoralis minor, and external intercostals. The muscles of expiration include: abdominals and internal intercostals.
What are the muscles known as neurovascular entrappers?
Scalene muscles(anterior & middle fibers) can entrap the lower trunk of the brachial plexus, causing neuropraxia of ulnar nerve
Where do the scalenes originate?
They originate from the transverse processes from the cervical vertebrae of C2 to C7 and insert onto the first and second ribs. Thus they are called the lateral vertebral muscles.
What neck muscles do rotation?
There are many more than two muscles in the neck that perform the action of rotation. Among the primary contributors are the sternocleidomastoid (SCM)-the visible muscle that runs from beneath your ear to the top of your sternum-and splenius cervicis at the base of the rear portion of the skull. Other muscles like your upper traps and levator scapulae also play a role, though not as significant.
What primary muscle responsible for elevating the ribs durning inspiration?
The pectoralis minor, scalenes and the external intercostals. This is sometimes referred to as 'back breathing' and when used to its full capacity, as in athletics or heavy breathing, it is measured by vital capacity. This is the amount of air that can be forcibly inhaled and exhaled in one breath.
The primary muscles involved in torticollis are?
The primary muscles involved in torticollis are the sternocleidomastoid muscle and the trapezius muscle. These muscles are responsible for controlling the position and movement of the head and neck. Injury or spasm of these muscles can cause the characteristic head tilt and rotation seen in torticollis.
