R2 Flashcards
are distingusihed by the shape of the vertebral body, the relative size of the vertebral foramen, the presence of costal processes with transverse foramen, and with spinous processes
cervical vertebrae
have a distinctive heart-shaped bodies, long, slender spinous processes, and articulations for the ribs
thoracic vertebrae
are the most massive and least mobile, they are subjected to the greatest strains
lumbar vertebrae
protects the reproductive, digestive, and excretory organs. has an auricular surface for articulation with the pelvic girdle. it articulates with the fused elements of the coccyx
sacrum
an s-shaped bone that extends between the manubruim of the sternum and the acromion of the scapula
clavicle
articulates with the round head of humerous at the gleniod cavity of the scapula.
scapula
articulates with the glenoid cavity of the scapula. anatomical.
humerus
____are parallel bones of the forearm. the olecranon fossa of the humerus accommodates the olecranons of the ulna during straightening of the elbow
ulna and radius.
forms two rowa, proximal and distal. from lateral to medial, the proximal row consist of scaphoid, lunate, tranqetrum and pissiform.
carpal bones
articulate with the distal carpal bones. distally articulates with the phalanges.
metacarpals
consist of two hip bones called the coxal bones. each hip bone forms through the fusion of three bone- ilium, ischium and pubis
pelvic girdle
the largest of the hip bone, inside the acetabulum, the hip is fused to ischium and pubis
ilium
consist of two hip bones, the sacrum, and the coccyx. maybe be subdivided into greater pelvis and lesser pelvis
pelvis
the largest bone in the border. has round head articulating with the pelvis at the acetabulum and at its distal end its medial and lateral condyle articulates with tibia at the knee joint
fumer
a large sesamoid bone that forms within the tendon of the quadriceps femoris muscle group
patella
a large medial bone of the leg. the prominent markings include tibia tuberosity, anterior margin, medial malleolus.
Tibia
is a slender leg bone lateral to the tibia. the head articulates with the tibia inferior to the knee, inferior slightly posterior to the lateral tibial condyle.
fibula
includes 7 bones, only the smooth superior surface of the trochlea of the talus articulates with the tibia and fibula.
tarsus
bony edges are close together and may interlock and also immovable.
synarthroses
Very limited movement are permitted
amphiarthroses
a wide range of movement is permitted at ____
diarthrosis or synovial joints.
are large diameter; they contain densely packed myofibrils, large glycogen reserves, and relatively few mitochondria
fast fibers
are only about half the diameter of fast fibers, and they take three times as long to contract after stimulation.
slow fibers
are very similar to fast fibers, although they have greater resistance to fatigue
intermediate fibers.
