Which structure is an example of a hinge joint? skull wrist knee hip description?

The correct answer is the knee.
A hinge joint, also known as ginglymus, is a joint in that allows bone movement in only one direction (motion only in one plane). The articular surfaces of the bones are connected by collateral ligaments. The best example of this type of joint is the interphalangeal joints of the hand. The knee also has hinge joints but less typical, because it allows a slight degree of rotation or of side-to-side movement in certain positions of the limb.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
