Study Notes
Joint Types and Movements
- The hip joint is classified as a ball-and-socket joint, allowing for a wide range of movement.
- The first carpometacarpal joint permits saddle movement, which facilitates opposition, allowing the thumb to touch the fingers.
- The elbow joint primarily allows for hinge movement, enabling flexion and extension of the forearm relative to the upper arm.
- Intercarpal joints facilitate gliding movements, allowing for slight shifts and adjustments between the carpal bones.
- The wrist joint, also known as the radiocarpal joint, allows for flexion, extension, and lateral movements.
Body Positions and Planes
- The anatomical position is characterized by arms abducted, palms facing forward, head and feet aligned and directed straight ahead.
- The sagittal plane divides the body into equal right and left halves.
- The transverse plane, perpendicular to the longitudinal axis, is referred to for various imaging and anatomical references.
- An x-ray is an image produced by the interaction of x-rays with an image receptor, representing the patient's anatomic structures.
Positioning Terms and Specific Positions
- Positioning terms define the orientation and placement of the body during imaging procedures.
- Lying on the back facing upward is called the supine position.
- The dorsal decubitus position involves lying on the back with the x-ray beam directed horizontally from the right side, exiting the left side of the body.
- The lateral decubitus position describes lying on the left side with the x-ray beam entering the posterior surface and exiting the anterior aspect.
- If a patient is recumbent and the right side is turned 15 degrees toward the image receptor, this is classified as a right anterior oblique position.
- Decubitus positions always utilize a horizontal x-ray beam for proper imaging.
