Q

Synovial Joints Based on Shape of Articulating Bones

Describe plane/gliding joints

A
  • flat articulating surfaces that permit the simplest kind of movement (side-side and back-forth)
  • least ROM of all synovial joints

translation

Ex: carpals, tarsals, ribs/vertebrae, knee (patella and femur)

Q

Major Ligaments of Joints

List the ligaments of the neck

A

Ligamentum nuchae (nuchal ligament)

21
Q

Major Ligaments of Joints

Describe the nuchal ligament

A
  • runs from EOP inferiorly to spinous process of C7 (typically. Sometimes goes to T1)
  • creates support in flexion of the head at the neck
22
Q

Major Ligaments of Joints

List the ligaments of the shoulder

A
  1. Acromioclavicular
  2. Coracoclavicular
  3. Coracoacromial
  4. Transverse humeral ligament
23
Q

Major Ligaments of Joints

Describe the acromioclavicular ligament

A

CT that holds clavicle to acromion

24
Q

Major Ligaments of Joints

Describe the coracoclavicular ligament

A

creates stability when there is pulling that may separate the scapula and clavicle

technically two parts to it, but refered to as a unit

25
Q

Major Ligaments of Joints

Describe the coracoacromial ligament

A

creates stability along the scapula to contrast the pull of pectoralis minor and brachial muscle

26
Q

Major Ligaments of Joints

Describe the transverse humeral ligament

A

support to keep bicipetal groove muscle in place

27
Q

Major Ligaments of Joints

Describe the inguinal ligament

A
  • runs from ASIS to pubis
  • control of coxal bone against all sorts of pulling from different directions
28
Q

Major Ligaments of Joints

Describe the sacrotuberus ligament

A

supports from PSIS along sacrum to ischial tuberosity

29
Q

Major Ligaments of Joints

Describe the posterior & anterior sacroiliac ligament

A

provide stability between sacrum and coxal bone

30
Q

Major Ligaments of Joints

List the ligaments of the hip joint

A
  1. Iliofemoral
  2. Ischiofemoral
  3. Pubofemoral
31
Q

Major Ligaments of Joints

Describe the ligaments of the hip joint specifically and how they differ from other ligaments of the body

A

curved to allow for more movement/ROM while maintaining stability

32
Q

Major Ligaments of Joints

List the ligaments of the knee

A
  1. Medial meniscus
  2. Lateral meniscus
  3. Tibial (medial) collateral
  4. Fibular (lateral) collateral
  5. Anterior cruciate
  6. Posterior cruciate
  7. Patellar
33
Q

Major Ligaments of Joints

Describe the tibial (medial) collateral ligament

A

MCL
- provides support on the medial knee
- prevents lateral tibial movement

34
Q

Major Ligaments of Joints

Describe the fibular (lateral) collateral ligament

A

LCL
- opposes purpose of MCL to support the lateral knee and prevent medial fibular movement
- tearing this can also happen with a sudden blow to the fibula

35
Q

Major Ligaments of Joints

Describe the anterior cruciate ligament

A
  • runs from posterior femur to anterior tibia
  • prevents posterior movement of the femur (aka anterior movement of tibia)
  • most commonly torn
36
Q

Major Ligaments of Joints

Describe the posterior cruciate ligament

A
  • runs from posterior tibia to anterior femur
37
Q

Major Ligaments of Joints

List the joints of the ankle

A
  • Medial/Deltoid ligament
  • Lateral ligaments
38
Q

Major Ligaments of Joints

List the 4 minor ligaments of the medial/deltoid ligament

A
  1. tibionavicular
  2. anterior tibiotalar
  3. posterior tibiotalar
  4. tibiocalcaneal
39
Q

Major Ligaments of Joints

Describe the medial/deltoid ligament

A
  • has 4 parts
  • create dense layer of CT on medial ankle
    * very difficult to strain
40
Q

Major Ligaments of Joints

Describe the lateral ligaments of the ankle

A
  • 90% of all ankle sprains
  • has 3 separate ligaments
41
Q

Major Ligaments of Joints

List the 3 ligaments of the lateral ankle ligaments

A
  1. inferior talofibular
  2. posterior talofibular
  3. calcaneofibular
