Muscle Types

• Striated Muscle

  • Non-voluntary movement

  • Appears with cross striations when observed under a microscope

Urinary Catheter Management

• Foley Catheter

  • If flushed too quickly, it may cause a spasm.

  • Resulting spasm leads to contraction of the bladder, resulting in discomfort or pain.

  • Similar reaction can occur with IV s (intravenous lines).

Fluid and Electrolytes

• Transport Mechanisms

  • Passive Transport

    • Moves substances along the concentration gradient (from high to low concentration).

    • Requires no energy expenditure.

    • Example: Diffusion of electrolytes through cell membranes.

  • Active Transport

    • Moves substances against the concentration gradient (from low to high concentration).

    • Requires energy (often in the form of ATP).

    • Example: Sodium-Potassium pump which maintains cell ion concentrations.

Understanding Active vs. Passive Transport

• Passive Transport:

  • "Go with the flow"; natural movement without energy.

• Active Transport:

  • Requires energy and effort, likened to needing strength to go against the current.

• Active Transport: Requires energy and effort, akin to needing strength to go against the current.
