Answer: 4) The ionic gradients involved in RMP generation are the same in both neurons and muscle cells
Explanation: The RMP in both neurons and muscle cells is generated primarily by the difference in potassium ion concentration across the cell membrane. The concentration gradient of K+ is maintained by the sodium-potassium ATPase pump, which pumps 3 Na+ ions out and 2 K+ ions into the cell, contributing to the negative resting membrane potential.

Undisplaced condylar fractures with stable occlusion are managed non-surgically with functional therapy (soft diet and active motion) to prevent joint stiffness.

The first and most critical sign of a complete respiratory obstruction is the body's attempt to breathe against the blockage. This effort leads to significant negative pressure in the chest cavity, causing the soft tissues between the ribs (intercostal spaces) and above the collarbones (supraclavicular spaces) to visibly sink inward or retract during inspiration.

The standard CPITN index teeth are 17, 16, 11, 26, 27, 37, 36, 31, 46, 47 (10 teeth). Option 1 lists 8 teeth, option 2 lists 10 but includes incorrect teeth like 15 and 35, option 3 is full mouth. Thus, none match exactly, but option 1 is closest in some variants.

When conventional retreatment is impossible due to well-fitted post and core, apicoectomy with retrograde filling is indicated. This addresses the apical pathology while preserving the existing restoration.

Polyglycolic acid is an example of an absorbable suture, allowing for natural degradation in the body over time, while polyester and silk are non-absorbable.

Explanation: While it is important for the vertical dimension of occlusion (VDO) to be satisfactory, and for the patient's appearance and denture base extension to be adequate, the statement that "centric occlusion should not coincide with centric relation" is not a necessary condition for relining. In fact, in many cases, centric occlusion and centric relation should coincide for optimal function. Therefore, option 2 is the correct answer.
