What is the name of the joint between the C1 and C2 vertebrae?
Atlantoaxial joint
What type of joint is between the C1 and C2 vertebrae?
Synovial pivot joint
What is the name of the joint between the cervical spine and the base of the skull?
C0-C1
Atlantooccipital joint
What is the type of joint between the cervical spine and the base of the skull?
Synovial condyloid joint also known as ellipsoid joint
How to remember C1 and C2 vertebrae?
C1 - Atlas - 5 letters which is odd like 1
C2 - Axis - 4 letters which is even like 2
What structure travels within the costal groove?
Posterior intercostal artery
What bones do the ribs articulate with?
Two thoracic vertebrae by the costovertebral joint which is a synovial plane joint
What two bones form the pectoral girdle?
Clavivle
Scapula
What bones form the pelvic girdle?
Iilum
Isschium
Pubis
What is the acetabulum?
The acetabulum is the “socket” of the “ball-and-socket” hip joint.
What does the acetabulum articulate with?
Head of the femur
How do the male and female pelvis differ?
Female pelvis has a shorter and wider cavity to support giving birth.
Male iliac crests are higher than females, causing their false pelves to look taller and narrower.
What is the function of the ischial spine?
Gives attachment to the gemellus superior on its external surface and to the coccygeus, levator ani, and pelvic fascia on its internal surface
What is the function of ischial tuberosity?
The ischial tuberosity is the lower part of your pelvis that’s sometimes referred to as your sit bones. It helps to absorb your weight when you sit.
Clinical significance of ischial spine
Landmark in pudendal anaesthesia, as the pudendal nerve lies close to the ischial spine.
Clinical significance of ischial tuberosity
It can also cause pain when a nearby fluid-filled sac, called the ischial bursa, becomes inflamed and causes ischial bursitis.
How are fibrous joints connected?
Fibrous connective tissue
What type of joint is the manubriosternal joint?
Synovial - secondary cartilaginous
What type of joint is the manubriosternal joint?
Secondary cartilaginous
What is the joint between a tooth and socket?
Fibrous joint
What are the key structural characteristics of a synovial joint?
Articular capsule
Articular cartilage
Synovial fluid
What range of movement do condyloid joints have?
Large
