Radiological anatomy of the Wrist Osseous Anatomy The osseous structures of the wrist are the distal portions of the radius and ulna, the proximal and distal rows of carpal bones, and the bases of the metacarpals (Fig. 1). The proximal row of carpal bones consists of the scaphoid, lunate, triquetrum, and the pisiform. The distal row of carpal bones contains the trapezium, trapezoid, capitate, and hamate bones. The distal row of bones articulates with the metacarpal bases.
2 Hip Muscles and Movements The hip joint is a multi-axial ball-and-socket joint, and therefore, movements along perpendicular planes occur over a wide arch of motion, namely flexion and extension, adduction and abduction, medial and lateral rotation, and circumduction . Muscles surrounding the hip are divided into groups; each is mainly, but not only, responsible for a certain movement of the hip. The main hip flexor is the psoas muscle, helped by the iliacus, but also other muscles assist in hip flexion. Extension is mainly performed by the gluteus maximus.
Anatomy Understanding the tibiofibular syndesmosis needs an inclusive knowledge of the surrounding anatomic structures. Talocrural joint The ankle, or talocrural joint, is a modified-hinge, uniaxial joint formed by the medial malleolus of the tibia, the talus and the lateral malleolus of the fibula. Specifically, the convexsuperior articular surface of the talus or trochlea articulates with the concave distal articular facet of the tibia. The medial malleolus articulates with the medial aspect of the trochlea whereas the lateral malleolus articulates with the lateral aspect of the trochlea.
Understanding the tibiofibular syndesmosis needs a hint of the surrounding anatomic structures. Talocrural and Subtalar Joints The ankle, or talocrural joint, is a modified-hinge, uniaxial joint formed by the medial malleolus of the tibia, the talus and the lateral malleolus of the fibula. Specifically, the convex superior articular surface of the talus or trochlea articulates with the concave distal articular facet of the tibia. The medial malleolus articulates with the medial aspect of the trochlea whereas the lateral malleolus articulates with the lateral aspect of the trochlea.
The synovial joints between the superior and inferior articular processes on adjacent vertebrae are termed the facet joints (also known as zygapophysial joints or Z-joints ). They permit simple gliding movements. The movement of the lumbar spine is largely confined to flexion and extension with a minor degree of rotation (see the image below). The region between the superior articular process and the lamina is the pars interarticularis. A spondylolysis occurs if ossification of the pars interarticularis fails to occur.
The Appendicular skeleton consists of: PECTORAL GIRDLE (consists of two shoulder blades and two collar bones, which articulate together to allow some movement). UPPER LIMBS (consists of upper arm, forearm, wrist, palm, and fingers that all work together for movement and function of your arm). PELVIC GIRDLE (two large hip bones that provide support for the attachment
The Patriots would get a few points before the Tigers would retaliate. After a long, tedious 3 sets, the Tigers were ahead 2-1. The fourth had just begun when the other team noticed a flaw in the Tiger’s positioning, and sent the ball speeding toward an open part of the court. Haley, the defensive specialist, saw the position of the opposing hitter’s arm and started running to the far right side of the court, knowing that the ball would land on the line and they would lose the first point if she did not move rapidly. She dove at the last second to reach where the ball would land, sacrificing her body to get the point, the ball then hit her hand and went spinning, back up to the center of the court, leaving a stinging sensation on Haley’s hand.
According to the text, it says that she “practiced shooting” to get accurate aim. After she found out that she didn’t have enough power in her thumb to move the marble far enough, she decided to exercise her wrists and fingers (specifically the thumb). First, she made her wrists more powerful by doing “twenty push-ups on her fingertips”. Then, she “squeezed a rubber eraser one hundred times.” These examples illustrate how Lupe put a lot of effort into learning how to become better at sports.
BACKGROUND AND LITERATURE REVIEW 2. Clinical Background 2.1 The human spine The human spine (also referred to as vertebral column or spinal column) is a bony structure in the middle of the back starts at the base of the skull and continues to the pelvis. It consists of vertebrae (small bones) and joints (intervertebral disks) together to form a flexible and stable spinal column.
Ego Trippin’ I was born to sing. My beautiful voice sounds like a cheerful bird busily chirping in the early morning sun. I can dance just as well, with my feet gracefully sliding across the smooth floor like a tiptoeing butterfly. The piano that I play bows down to me as I gently push down each and every one of its soft, white and black keys.
