Description The hand’s tiny intrinsic muscle is known as the Opponens Pollicis. Along with the adductor pollicis, abductor pollicis, and flexor pollicis brevis, it is a part of the thenar muscles group. The thenar eminence is an eminence originating from the thenar muscles on the lateral side of the hand. The opponent’s pollicis runs through…
Description The flexor pollicis brevis is the name of the tiny and broad intrinsic muscle of the hand. It is a part of the thenar muscles grouping together with the opponens pollicis, adductor pollicis, and abductor pollicis brevis. The heads of the flexor pollicis brevis are superficial and profound. The deep head, on the opposite…
Description A hand muscle called the adductor pollicis is located in the palm of the hand, particularly near the base of the thumb. The oblique head and the transverse head are their two components. The transverse head develops from the distal third of the ulna and the interosseous membrane, whereas the oblique head comes from…
Description The short intrinsic muscle is known as the abductor digiti minimi of the hand. It belongs to a group of muscles that impact the fifth finger. The muscles of the hypothenar region are the flexor digiti minimi brevis and the opponens digiti minimi. The main actions of the abductor digiti minimi are the abduction…
What is Abductor pollicis brevis muscle? The abductor pollicis brevis muscle is a hand muscle located at the base of the thumb that is responsible for abducting the thumb away from the palm. It is innervated by the median nerve and is important for thumb movement and grip strength. Injuries or conditions that affect this…
Introduction The hard system of the thoracic pit is known as the ribs. All vertebrates are curved, narrow, and flat strips of bone. The rib cage is formed by attaching it dorsally to the vertebrae and ventrally to the breast bone (sternum). In the human body, the rib confine is a bin-like construction that is…
Description The extensor pollicis brevis muscle is a skeletal muscle situated in the hand that is responsible for extending the thumb at the carpometacarpal joint (base of the thumb). It arise from the distal 3rd of the posterior surface of the ulna bone and the interosseous membrane and inserts into the base of the proximal…
Description The flexor pollicis longus muscle is a deep muscle located in the anterior compartment of the forearm. It is one of the muscles responsible for flexing the thumb or pollex. The muscle originates from the anterior surface of the radius and the interosseous membrane, which connects the radius and ulna bones of the forearm….
Description Flexor digiti minimi brevis is a short intrinsic hand muscle. It corresponds to the group of muscles classified as the hypothenar muscles, together with the abductor and opponens digiti minimi. The hypothenar prominence is an extension that they developed over the tiny finger’s base. The flexor digiti minimi brevis goes from the flexor retinaculum…
Introduction The sternum is the centrally located anterior portion of the chest wall and is a partially T-shaped vertical bone. There are three anatomical divisions in the sternum: the manubrium, body, and xiphoid process. The anterior rib cage’s costal cartilage connects the sternum to the ribs. The xiphoid process is the narrower distal segment that…
