Pelvis Flashcards
Iliac crest
Palpation: Start at ribs, fell down along the ridges of the illium bone.
1) Part of the illium bone, the most prominant part.
2) Allows attatchment of external and internal obliques, Transverse abdomilis. From the leg includes the tensor fascia latae. Also include latissimus dorsi from the back and errector spinae muscles.
Anterior superior illiac spine
Palpation: Feel along crest until reaching first prominent bit.
1) Part of the ishium bone
2) Muscles that attatch include the sartorius, tensor fascia latae and for the limguinal ligament.
3) Underneath their is a AIIS, which is another important feature of the pelvis, like rectus femoris or ligaments (iliofemoral).
Posterior superior iliac spine
Palpation: Start at iliac crest, feel downwards until feeling protrusions.
1) Part of the ischium bone.
2) Attatchment site for gletus maximus and maltifidus and multiple ligaments.
3) Talk about ASIS.
Sacroiliac joint
Palpation: Between the sacrum and ilium bones.
1) A joint between the sacrum and ilium bones.
2) A synovial joint.
3) It allows the movement of weight between upper body and legs.
4) Other ilium land marks/pubic symphsus.
Ishial tuberosities
Palpation: At the very bottom of the ishial bones.
1) Part of the ishial bone, located posteriorly.
2) Attachment point for the hamstrings, biceps femoris, semitendinosis and semimembranosis and adductor magnus.
3) Commonly refered to as the sitting bones, it bares weight whilst in a sitting position.
4) Obturator foramen above it, which allows the obtrator nerve artey and vein to pass through.
Symphysis pubis
Palpation: At the front between the pubic bones.
1) Joint between left and right pubic bones.
2) Is a cartilagenous joint, so it allows very little movement, making it sturdy and strong.
3) This allows it to bear the weight of the body, before it travels downards.
4) During childbirth, the ligaments become flexible to allow for the child to pass through.
5) Also located directly in front of the bladder.
