Answer:
- fibrous joint between radius and ulna: C. syndesmosis
- fibrous joint that unites bones of the skull: H. suture
- articulation between teeth and bone: J. gomphosis
- joint with a cavity between bones: E. synovial
- the epiphyseal plate: F. synchondrosis
- articulation between two pubic bones: A. symphysis
- permits opposition and reposition: B. saddle
- fibrocartilagenous fluid filled sacs outside the joint cavity: G. meniscus
- most common degenerative joint disease: D. osteoarthritis
- movement of the sole laterally: I. eversion
Explanation:
The syndesmosis can be defined as a fibrous joint held together by ligaments. Sutures are fibrous joints of tissue that link the cranial bones of the skull. A gomphosis is a mobile fibrous that binds the teeth into sockets in the mandible and maxilla. Synovial joints are joints found between bones that move against each other (e.g., shoulder bones). They (synovial joints) are the most common class of joints found in the body. A symphysis is a cartilaginous, slightly movable, joint between two bones. A saddle is a synovial joint whose opposing surfaces are concave and convex, respectively. Osteoarthritis is the most common type of arthritis, this condition occurs when the protective cartilage surrounding the bones wears away over time. Finally, eversion refers to a type of movement of the foot which occurs in the auctioneering joint.
Answer:
In acupressure, pressure points are thought to be powerfully sensitive parts of the body. Some people believe that by applying pressure to our body’s pressure points, it can help relieve pain, establish balance, and improve health throughout the body.

Explanation:
Action potential can be split into 5 phases (0-4), where phase 4 leads from one action potential to the next. Phase 0 is the line up and is known as depolarization, it is here where the action potential is triggered and fast Na channels will open. Next, is phase 1 called early repolarization which is the little bit at the beginning of the plateau-here the Na channels will close. Then you have the plateau phase where Ca channels are open at the beginning and close at the end. Then is phase 3 called repolarization which is the big slope down and here is where the normal transmembrane ionic concentration gradients are restored. Finally, phase 4 which is the resting phase occurs. There are many resources online if you need more details, here is a pretty good one: http://www.pathophys.org/physiology-of-cardiac-conduction-and-contractility/
