Lateral antebrachial cutaneous nerve – Anatomy Course A continuation of the musculocutaneous nerve in the arm. This nerve becomes the lateral antebrachial cutaneous nerve once it has emerged from between the biceps brachii and the brachialis muscle, lateral to the biceps brachii tendon, passing behind the cephalic vein. It then divides into two branches, both
April: In an interesting and significant coincidence, April is celebrated in the U.S. and several other countries as an awareness month for the following social and sexual health topics: use and mis-use of alcohol, sexual assault awareness, and sexually transmitted diseases. These three more “social” topics and the places where they intersect are the themes
Health can be defined in several ways, from the very narrow consideration of the absence of disease: “healthy cells” that function in a body to keep that body working to its maximum capacity and capability, to the broader sense of “a state of complete physical, mental, and social well-being and not merely the absence of
Omohyoid Anatomy Origin: Superior border of scapula medial to suprascapular notch. Insertion: Body of hyoid bone. Key Relations: Is one of the infrahyoid muscles (sometimes referred to as ‘strap muscles’) lying in the muscular triangle of the neck. Lateral to sternohyoid. Functions Depresses and fixes the hyoid bone. Supply Nerve Supply: Anterior rami of C1
Subcutaneous prepatellar bursa Anatomy Subcutaneous Prepatellar Bursa is situated in front of the patella bone. Functions Acts as a cushion between bone and skin reducing friction between both. Clinical Prepatellar bursitis or ‘housemaid’s knee’ is a common injury to the bursa. The bursa becomes swollen due to repetitive work in a kneeling position.
Acromioclavicular Joint / Motion The acromioclavicular joint is classified as a multiaxial synovial plane joint but it is more helpful to think of it as a pivot point. As the name suggests it is the articulation of the acromion of the scapula with the clavicle. It allows you to raise your arms above your head
Trapezius / Anatomy Origin: Superior nuchal line of the occipital bone, external occipital protuberance, ligamentum nuchae and spinous processes of C7 to T12. Insertion: Superior fibres: posterior border of the lateral third of the clavicle. Middle fibres: medial border of the acromion and the superior edge of the spine of the scapula. Inferior fibres: tubercle
Hyoid – Anatomy Hyoid is a Lingual bone, U-shaped, in front of neck, between larynx (behind) and mandible (in front), at level of C3; made up of body (transverse), greater horns/cornus (long, pointing back), lesser cornus/horns (short, pointing up); suspended from tips of styloid processes of mandible by ligaments (this syndesmotic connection being its only
