The diagnosis requires x-rays of the pelvis, with anteriorposterior (AP) and frog-leg lateral views. [11] The appearance of the head of the femur in relation to the shaft likens that of a "melting ice cream cone", visible with Klein's line. The severity of the disease can be measured using the Southwick angle. [citation needed]
The mating period of these frogs is during the fall and winter seasons. These frogs call usually during the morning and mid-afternoon hours. [15] Males of this species do not attract females with croaks, instead producing a sharp clicking sound by snapping the hyoid bone in their throats. [16] The clicking sound resembles metallic noises.
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
A pair of clicking stream frogs (Strongylopus grayii) in amplexus Orange-thighed frogs (Litoria xanthomera) in amplexusAmplexus (Latin "embrace") is a type of mating behavior exhibited by some externally fertilizing species (chiefly amphibians and horseshoe crabs) in which a male grasps a female with his front legs as part of the mating process, and at the same time or with some time delay, he ...
A nuptial pad (also known as thumb pad, or nuptial excrescence [1]) is a secondary sex characteristic present on some mature male frogs and salamanders. [2] [3] [4 ...
Two historic outbreaks of priapism have been linked to consumption of frog legs from frogs that ate insects containing cantharidin. [21] African clawed frogs in the wild are found at higher densities in artificial water bodies, such as ponds, dams and irrigation canals, rather than in natural lagoons or streams or rivers.
Patagia on a flying squirrel. The patagium (pl.: patagia) is a membranous body part that assists an animal in obtaining lift when gliding or flying.The structure is found in extant and extinct groups of flying and gliding animals including bats, theropod dinosaurs (including birds and some dromaeosaurs), pterosaurs, gliding mammals, some flying lizards, and flying frogs.
The infrapatellar fat pad (Hoffa's fat pad) is a cylindrical piece of fat that is situated inferior and posterior to the patella bone within the knee, [1] intervening between the patellar ligament and synovial fold of the knee joint.
