Human Anatomy 101 Flashcards
Name one muscle that attaches to the iliac crest
external oblique/ internal oblique
What muscle passes through the greater sciatic foramen?
piriformis muscle
What two blood vessels pass through the greater sciatic foramen?
inferior gluteal artery and vein / internal pudendal artery and vein
What four nerves pass through the greater sciatic foramen?
posterior cutaneous nerve of thigh, nerve to quadratus femoris (L4-S1 of sacral plexus), pudendal nerve, sciatic nerve
(mnemonic = PIN/ PINS/ SNIP/ NIP
What artery passes through the lesser sciatic foramen?
pudendal artery and vein
What muscle passes through the lesser sciatic foramen?
obturator internus tendon
What nerve passes through the lesser sciatic foramen?
pudendal nerve
What are examples of an amphiarthrosis secondary cartilaginous joint, and what type of cartilage are they made from?
intervertebral joints/ discs and sacrococcygeal joint, fibrocartilage and hyaline cartilage
What are examples of an amphiarthrosis primary cartilaginous joint, and what type of cartilage are they made from?
epiphyses of long bones and costochondral joints, hyaline
What are some examples of hyaline cartilage?
thyroid, cricoid and trachea
What nerve passes into the true pelvic cavity, anterior to the ala of the sacrum?
lumbosacral nerve trunk
What structures pass through the tarsal tunnel?
calcaneal tendon, flexor hallucis longus tendon, flexor digitorum longus tendon, tibialis posterior tendon, tibial nerve, posterior tibial artery
What structures define the boundaries of the tarsal tunnel?
medial malleolus, calcaneus, flexor retinaculum
What is the interosseous talocalcaneal ligament’s function?
helps to stabilise the subtalar joint along with the cervical ligament. The primary function of the cervical ligament is to resist excessive joint supination whereas the ITC ligament remains taut during pronation.
What is one function/ clinical significance of the plantar aponeurosis/ fascia?
maintains longitudinal arch, protects deeper structures/ plantar fasciitis
What muscle tendons travel, along with the deep fibular nerve and vessels, deep to the extensor retinaculum?
tibialis anterior, extensor hallucis longus, extensor digitorum longus, fibularis tertius
