What is the name of the joints indicated by #5?	Zygapophyseal Joints
The body of what vertebra articulates with the superior articular process of the sacrum to form the lumbosacral joint?	L5
What's the "bony" part of your butt actually called?	The Ischial tuberocity
What's this called?	Sacral Tuberocity
True or false: The sacral tuberocity is considered part of the lumbosacral joint	True Slides: "The sacral tuberosity is another surface of the sacrum that unites with the hip bones to form the sacroiliac joints"
The _______ surface of the ilium, and the _______ surface of the sacrum are articular surfaces of the sacroiliac joint.	Auricular
_____________ is a rotational, or "tilting", movement of the sacrum about an axis located at the attatchements of the interosseous sacroilkiac ligamanets.	Nutation
All symphyses occur in the _______ of the body	Midline
What cartilage is a precursor for bone? (Not in slides, but important; hint is from slides)	Hyaline Cartilage
The paired hip bones that make up the pelvic girdle are connected to each other at the cartilaginous pubic symphysis. What is the subsequently created stable area, highlighted in red, called?	Pelvic Ring
The hip joint, scientifically referred to as the _____________ joint	acetabulofemoral
The hip joints are the most important mechanical part in retaining _______.	Balance
What kind of joint is this?	Triaxial
What is the ligament indicated by #1?	Anterior Sacroiliac Ligaments
What is the ligament indicated by #2?	Sacrospinous Ligament
What are the names of the 3 EXTERNAL ligaments that encapsulate the acetabulofemoral joint? Bonus if you know which is which	Iliofemoral Ligament (red), Ischiofemoral Ligament (blue), Pubofemoral Ligament (green)
Which bone is smaller, the tibia or fibula?	Fibula
The lateral end of the fibula is called what?	Lateral malleolus
The knee joint is the largest and most complex joint of the body. What is its scientific name?	tibiofemoral joint
Three bones articulate at the knee joint, BUT only 2 bones are actually PART of the knee joint. What two bones are ACTUALLY considered part of the joint?	Fibula, patella
What am I? A small, fluid-filled pocket that forms in connective tissue. They often form where a tendon or ligament rubs against other tissues. Located around most synovial joints, including the knee joint, these reduce friction and act as shock absorbers.	A bursa
What am I? A pad of fibrocartilage between opposing bones within a synovial joint. These articular discs may subdivide a synovial cavity, channel the flow of synovial fluid, or allow for variations in the shapes of articular surfaces.	Meniscus
What am I? Supports, strengthens and reinforces synovial joints.	Accessory ligaments
What shape are the medial and lateral menisci in the knee similar to?	A crescent (moon)
With their different curvatures, the ___________ compensate for the mismatch in articulating surfaces of the femur and tibia. They absorb approximately 1/3 of the loads imposed on the knee.	Menisci
What is one of the two main jobs of the cruciate ligaments (ACL/PCL)?	1) Keeps the articular surfaces of the femur and tibia in contact 2) while stabilizing the knee joint.
What's the name of the ligaments on the outside of the knee?	Collateral Ligaments
True or false: The Gluteus Maximus originates at the posterior illium, and sacrum and inserts at the ischium (your "butt bone") on the lower pelvis.	False. Your gluteus maximus DOES originate at the posterior ilium, and sacrum, BUT it inserts at the lesser trochanter.
Which image represents the anterior view of the femur? The one on the left, or the one on the right?	Right side.
What is the structural purpose of the lateral malleolus of the fibula?	To provide stability to the ankle (joint).
What is this process called?	Head of the fibula
What is this? A gliding joint between the distal ends of the tibia and fibula and the proximal end of the talus	"Ankle Mortise" (From Middle English "morteys", from Old French "mortaise", from Arabic مورتاز‎ ("murtazz", “fastened”), from راز‎ ("razza", “to cut a recess”).)
The knee joint contains two identical joints. What are they called?	tibiofemoral joints
Where the thigh bone meets the knee cap is called that _____ joint.	Femeropatelar Joint
Which is larger: the medial meniscus or the lateral meniscus?	The medial
The menisci of the knee are found where?	Tibial Plateau
True or false: The menisci don't budge in their place to better support the knee, at all positions.	False
What tendon attaches the patella to the tibia?	Patellar Tendon
