Skeletal System

The clavicle acts as a brace to hold the arm away from the thorax by connecting the arm to the body. It does not have a direct role in allowing movement of the shoulder joint, protecting the spinal cord, aiding in digestion, or supporting the lower back.

The scapula is a flat, triangular bone located on the posterior aspect of the shoulder. It is not directly attached to the axial skeleton such as the skull, spine, and ribs. Instead, the scapula is held in place by various trunk muscles allowing it to move freely for arm and shoulder movements.

The Medial Sternal End corresponds to option 2 in the picture, which is correctly labeled as the location. Options 1, 3, and 4 are incorrect choices as they do not correspond to the Medial Sternal End.

The correct term for the end labeled as #1 in the picture is the Lateral Acromial End, as it refers to a specific location on the structure being referred to.

The Acromion Process connects with the Clavicle, forming part of the shoulder joint.

The biceps muscle attaches to the Coracoid Process, which is represented by #11 in the picture. This attachment point allows the biceps muscle to function properly in moving the arm.

The Glenoid Cavity is a socket located on the scapula that receives the head of the humerus, forming the shoulder joint. Option 1 is incorrect as it describes a different area. Option 3 is incorrect as it misidentifies the location of the joint. Option 4 is incorrect as it describes a bony projection unrelated to the Glenoid Cavity.

The Suprascapular Notch is a passageway for nerves located at position #13 in the picture. It allows nerves to pass through and innervate the muscles and skin in the shoulder region.

The spine refers to the #8 vertebrae in the picture, which is the correct answer. This vertebrae plays a crucial role in providing structural support and protection to the spinal cord.

The superior angle refers to the angle #10 in the picture that is located at the top position compared to other angles in the same figure.

A lateral angle is an angle formed when two lines intersect. It is the angle on the outside of the angles produced by the intersection.

The Inferior Angle is the angle labeled as #5 in the picture as it is located at the bottom of the shape.

The Medial Border refers to the inner edge of the structure being identified. In this case, option #6 in the picture represents the correct placement for the Medial Border.

The Lateral Border is indicated by the number 5 in the picture, which is located on the outer side of the object.

In medical anatomy, the term Superior Border is used to describe the upper edge of an organ or structure. It is an important reference point for identifying the positioning and orientation of various body parts.

The Supraspinous Fossa is located in the spine where the spine ends and the back begins, it is a shallow depression above the spine that can be felt when touching the spinal column.

The Infraspinus Fossa is correctly identified as #7 in the picture. It is a depression located on the dorsal side of the scapula below the spine.

The pectoral girdle connects the upper limbs to the rib cage, serving as a framework for arm movement. It is not a complete ring like the pelvic girdle. The incorrect answers do not accurately describe the function of the pectoral girdle.

The appendicular skeleton consists of the bones of the upper and lower limbs, including the shoulder girdle and the pelvic girdle. It does not include the skull, spine, or rib cage, which are part of the axial skeleton.

The word 'Humerous' is often confused with 'Humorous', which means funny or amusing in character. However, the correct meaning of 'Humerous' refers to the upper arm bone in the human body.

The head of humerus fits into the glenoid cavity of the scapula, forming the ball-and-socket joint of the shoulder.

The Greater Tubercle is a prominent projection on the proximal end of the humerus bone in the shoulder region, serving as the attachment site for multiple muscles involved in shoulder movement.

The Lesser Tubercle is a bony prominence located on the proximal part of the humerus bone. It serves as an attachment site for the subscapularis muscle, which is an important muscle of the shoulder joint.

The correct answer is #4, which is the Intertubercular Groove. It is located between the tubercles of the humerus and serves as the attachment site for the tendon of the long head of the biceps brachii muscle.

The Deltoid Tuberosity is located at #3 in the picture, which is a rough, triangular area on the lateral surface of the humerus where the deltoid muscle attaches.

A radial groove is typically found on certain objects or surfaces where the groove or indentation extends outward from a central point in a radial pattern.

The Lateral Epicondyle is typically located on the distal end of the humerus bone, serving as an attachment point for various forearm muscles. In the provided picture, #11 accurately represents the Lateral Epicondyle.

The Medial Epicondyle is located at the inner part of the humerus bone in the elbow joint, which corresponds to number 7 in the picture.

Captiulum refers to #5 in the picture, which is the correct identification of the item.

The trochlea is the part marked as #6 in the picture, which is an anatomical structure in the body that plays a role in movement.
