As triceps brachii does not supinate or pronate
the forearm, which bone of the forearm must it
be attached to distally? Correct Answers Ulna
At your wrist and on the skeleton, locate the bump on the medial
posterior aspect of the wrist. Which bone are you palpating?
Correct Answers Ulna
Based on its location across the shoulder joint
what is the main movement that concentric
action of deltoid would produce? Correct Answers Abduction
Bone heals faster than ligament when
damaged. Why do you think it takes so long
for DFCT structures to heal? Correct Answers Because of its
poor blood supply (less
vascular)
Compare the elbow (and in particular the articulation between
the humerus and the ulna) to the equivalent joint in the lower
limb (the knee). What difference do you notice in
terms of the fit of the bones in these two joints? Correct
Answers The humerus and ulna fit together very well,
creating a stable joint compared to the knee
joint.
Describe the structure of the knee joint Correct Answers The
knee joint is the joint between the condyles
of the femur and the proximal tibial surface.
, This is a synovial joint of the condylar type.
The movements are flexion, extension and some
rotation (but only if the knee is semi-flexed).
do you think that quadriceps femoris is resting or
active when standing in the anatomical
position? Correct Answers Resting. The quadriceps
tendon/ligament is
loose as no muscle activity results in no
tension in the tendon/ligament.
Does the clavicle articulate with the humerus? Correct Answers
No
From the location of the collateral ligaments
deduce what movements they would allow
and which they would restrict? Correct Answers Allow:
flexion and extension
Prevent: abduction and adduction
How are the menisci held at the joint Correct Answers The
menisci are attached peripherally
to the articular surface allowing some
movement of the menisci as the joint is
moved.
How are the phalanges structured Correct Answers The
phalanges decrease in size towards the tips of the digits. Note
that they also have distal heads and proximal bases.
