How the bones of lower limb articulate?
Depends on which lower limb bones your talking about. The head of the femur and pelvic girdle form the coxal joint, which is a deep ball and socket joint. Whereas your knee, tibiofemoral joint, and your ankle, talocrural joint, are both hinge joints. But its hard to tell from your question exactly what information you are looking for. Maybe your looking for the word diarthrosis, as the knee, hip, and ankle are synovial joints. Unless you are looking for the movements produced by these joints, which would be flexion, extension, laterial and medial rotation, abduction and adduction for the coxal joint. Flexion, extension, lat and med rotation for the tibiofemoral joint. Flexion, extension, lat and med rotation, plantarflexion and dorsiflexion for the talocrural joint.
What are the names of all 126 appendicular bones?
Appendicular Skeleton (126 bones) Pectoral girdle (4) Scapula (2) is commonly called the shoulder blade. It is supported and positioned by the skeletal muscles. The scapula has no bony or ligamentous bonds to the thoracic cage, but it is extremely important for muscle attachment. Clavicle (2) is commonly called the collarbone. It articulates with the manubrium of the sternum, and is the only direct connection between the pectoral girdle and the axial skeleton. Upper Limbs (60) Humerus (2) extends from the scapula to the elbow. Radius (2) lies along the lateral side (or thumb side) of the forearm. Ulna (2) forms the medial support of the forearm. Carpals (16) consist of 8 pairs of bones of the wrist and, composed of: four proximal bones (scaphoid, lunate, triangular or triquetral, and pisiform); four distal bones (trapezium, trapezoid, capitate, and hamate). Metacarpals (10) consist of 5 pairs of bones that articulate with the distal carpal bones forming the palm of the hand. Phalanges (28) consist of 14 pairs of finger bones. Four fingers contain three phalanges while the pollex (thumb) has only two. Pelvic girdle (2) articulates with the femur. Os coxae (2) is commonly called the hip bone. It is formed from a fusion of three bones (ilium, ischium, and pubis). Lower Limbs (60) Femur (2) is commonly called the thigh bone. It is the longest, strongest, and heaviest bone in the body. Distally, it articulates with the tibia at the knee joint. The head (epiphysis) articulates with the pelvis at the acetabulum. Tibia (2) is commonly called the shinbone. It is the large medial bone of the leg, attached to the patella by a ligament. Fibula (2) parallels the lateral border of the tibia. Patella (2) is the knee cap. Tarsals (14) consist of 7 pairs of bones (talus, calcaneus, navicular, cuboid, and the 1st, 2nd, and 3rd cuneiform bones). Only the talus articulates with the tibia and fibula. Metatarsals (10) support the sole of the foot and numbers I to V from medial to lateral with the distal ends forming the ball of the foot. Phalanges (28) have the same arrangement as with the fingers and thumb only with the toes and great toe (hallux)
What does the word "unremarkable" in an MRI scan report mean?
In medicine, unremarkable can loosely be defined as “nothing ununsual”. Perhaps the MRI was carried out to determine abnormal findings in the surrounding eye structures (muscles,nerves,vessels) perhaps like a mass or hemorrhage etc. But the MRI result showed nothing like what was expected, in this case medical doctors would just key in “unremarkable” in the report.If you are interested to find out more about medicine do check out my blog Medical Essential
Is there anatomical term for the Shoulder?If not why??
the muscle is deltoid the joint is acromion the bones are either clavicle, humerus, or scapula
What are the special features of the humerus bone?
The humerus, or arm bone, is the longest and larges bone of the upper extremity. It articulates proximally with the scapula in a ball joint, and distally at the elbow with both the ulna and radius in a hinge joint. The proximal (top) end of the humerus consists of a head that articulates with the glenoid cavity of the scapula. It also has an anatomical head, which is an oblique grove just distal (below) to the neck. The lesser tubricle is an anterior projection. Between these tubrecles runs an inter-tubercalur sulcus (bicipital groove). The surgical neck is a constricted portion just distal to the tubricles. It is so named because of its liability to fracture. The body (shaft) of the humerus is cylindrical at its proximal end. It gradually becomes triangular and is flatted and broad at its distal end. Along the middle portion of the shaft, there is a roughened, V-shaped area called the deltoid tuberosity. This area serves as a point of attachment for the deltoid muscle. The following parts are found at the distal end of the humerus: The capitulum is a rounded knob at that articulates with the head of the radius. The radial fossa is a depression that receives the head of the radius when the forearm is fixed. The trochlea is a pulley-like surface that articulates with the ulna. The coronoid fossa is an aterior depression that receives part of the ulna when the forearm is fixed. The olecranon fossa is a posterior depression that receives the olecranon of the ulna when the forearm is extended. The medial epicondyle and lateral epicondyle are rough projections on either side of the distal ened.
What is the connection point between the axial skeleton and appendicular skeleton?
The shoulder and pelvic girdles, functionally; the sternoclavicular articulation and sacroiliac joint, at the strictly skeletal level.
How many vertebrae bones does a human usually have?
A human being is born with 33 vertebrae. However, in the adult human body, 9 of these are fused together to form two bones known as the sacrum and coccyx.
