Hand quiz
Lay one hand flat on the table, palm down. Keeping the palm, fingers, and thumb flat on the table, slide your thumb back and forth, from the side of the hand. This motion is identified as: _________ Abduction and adduction of the thumb
radial
The lumbar spinal region is particularly prone to disc herniation (or a bulging disc) due to its high load bearing requirements and vulnerable ligamentous support:
true
How does her kyphotic posture interfere with ventilation in terms of its impact on volume and pressure?
Decreases Intrathoracic volume, which increases pressure, and limits inhalation/inspiration (due to both less space for lung expansion and increased pressure pushed out)
Your client is slowly sitting down onto the toilet from a standing position. During this action the prime mover of the knee joint and the type of contraction are best defined as:
eccentric contraction of the quadriceps
Which muscle fibers would be MOST responsible for the action of scapular retraction during a concentric contraction?
-middle trapezius
Loss of median nerve would MOST LIKELY result in:
When a person is sitting down and then bends to their feet to tie their shoes, what muscle group is performing what type of contraction?
spinal extensor group, contracting eccentrically due to gravity pulling them down
In terms of limiting her ventilation, Maureen’s condition of a punctured lung will first and foremost impact her lungs Volume or Pressure?
PRESSURE – The “hole” in the lung is like a leak in a balloon, impacting its capacity for pressure with air in or out. Volume is not impacted as this is controlled by the muscles and the thorax is not affected by lung damage.
Due to the difference in air
The Anterior Cruciate Ligament prevents posterior tibial displacement.
false
Choose the one shoulder joint below that is not a true joint.
-scapulothoracic joint
Paralysis of the dorsal interossei (inability to contract) would make it difficult to hold sand and or water in your hand and fingers. True or False
False
Anterior pelvic tilt refers to the iliac crest of the hip bones:
-Rotating forward (more anteriorly)
Maureen's limited ability to take deep breaths also limits her ability to cough forcibly. Considering her overall health, what does her inability to cough forcibly put her at risk for?
This is limited forced expiration which creates a “choking” concern, and/or issues of aspiration or getting food into airway (which can lead to pneumonia)
During the motion of Sit → to → Stand, the best descriptions of the joint actions that occur are the:
hips and knees are extending
Place your hands on the top of your head; then spread elbows back as far as possible (as in the image.) Which primary scapular motion occurs during this action?
scapular retraction
Which of the following is NOT an example of using intrinsic muscle(s) of the hand?
Touching the tip of 1st digit to the tip of 5th digit (using hypothenar and thenar eminence muscles)
Extending 2nd and 3rd digit, DIP, PIP, and MCP joints (extensor digitorum)
Squeezing sides of digits 2 through 5 together (adduction of interossei muscles)
Flexing MCP while extending PIP and DIP of digits 2 through 5 (lumbrical)
Extending 2nd and 3rd digit, DIP, PIP, and MCP joints (using extrinsic muscles)
Unilateral contraction of the right sternocleidomastoid would most likely result in:
right lateral flexion and cervical rotation to the left
Consider the Heimlich maneuver being performed on a person. -What phase of ventilation would this simulate? Forced expiration
-What muscles of ventilation would be activated during this phase? Forced expiration: abdominals, internal intercostals, quadratus lumborum
-Would the muscles above be contracting concentrically or eccentrically?
1) Forced expiration
2) Forced expiration: abdominals, internal intercostals, quadratus lumborum
3) concentrically
The action of flexing the hip while simultaneously extending the knee results in passive tension most significantly in the _______ muscles.
hamstrings
Getting your phone out of the back pocket of your jeans involves an active concentric contraction of the Anterior Deltoid muscle.
false
You are holding a large orange in your palm with your forearm supinated. Your hands are MOST LIKELY utilizing which group?
spherical
A person is lying supine. Part 1: they complete the “up” portion of a sit-up/crunch. Part 2: They then lower back DOWN. Part 2 (down) is best described as a (or an) ______ contraction of _____ muscles:
eccentric, anterior trunk
Place both hands on your lateral lower ribs. Breathe normally and feel what is moving. Then, with your hands still in place, forcibly inhale and exhale. Now what do you feel? What do you feel differently between forced and quiet inhalation and exhalation?
Quiet inspiration: Diaphragm and external intercostals contract which increases intrathoracic volume → decreases pressure and air pulls in
Forced inspiration: Scalenes and Sternocleidomastoid muscles added to muscles of quiet inspiration in order to increase intrathoracic volume → decreases pressure and air pulls in
Quiet expiration: All inspiration muscles relax which decreases intrathoracic volume → increases pressure and air pushes out
Forced expiration: Internal intercostal muscles, abdominal muscles, quadratus lumborum contract to forcibly decrease intrathoracic volume → increasing pressure which forcibly pushes air out
Imagine standing on both legs and feet remaining on the ground. Rotate the Right hip anteriorly, and Left hip posteriorly, as far as possible, in other words, rotate your trunk to the left as shown in the picture. What is this end position?
-left hip is internally rotated
When describing overall properties of the shoulder muscles, which of the following is NOT accurate?
a. The Distal Mobilizers typically “end” on the humerus
b. Proximal Stabilizers are commonly utilized when reaching up
c. Proximal Stabilizers “start” on the humerus and “end” on the scapula
d. Distal Mobilizers are largely responsible for actual humeral motion
C.
