Study Notes
Atlas and Axis Articulation
- The superior articular facets of the atlas (C1) are specifically shaped to articulate with the occipital condyles.
Lumbar Vertebrae
- Bifid spinous processes are typical of cervical vertebrae, not lumbar vertebrae.
- All lumbar vertebrae possess a vertebral foramen, large vertebral body, and mammillary process.
Humerus and Ulna Articulation
- The trochlea of the humerus articulates primarily with the trochlear notch of the ulna.
Forearm Interosseous Membrane
- The interosseous membrane of the forearm attaches between the radius and ulna.
Sternal Angle
- The sternal angle (Angle of Louis) is located at the level of the T4/T5 vertebral disc.
Sacrum
- The sacrum has four pairs of sacral foramina.
- It articulates with the ilium at the sacroiliac joint.
- It does articulate with the coccyx.
Medial Longitudinal Arch
- The talus bone contributes to the medial longitudinal arch of the foot.
Talus Articulation
- The articular surface of the talus that contacts the tibia is called the trochlear surface.
Linea Aspera
- The linea aspera is found on the posterior surface of the femur.
Costal Groove
- The costal groove on ribs contains the intercostal vessels and nerves.
Pterygoid Processes
- The pterygoid processes are part of the sphenoid bone.
Bones of the Orbit
- The temporal bone does not participate in the formation of the orbit.
- The orbit is formed by the lacrimal, sphenoid, and ethmoid bones .
Nasal Septum
- The inferior nasal concha does not form part of the nasal septum.
- The nasal septum is formed by the vomer, perpendicular plate of the ethmoid, and septal cartilage.
Uncinate Process
- The uncinate process is found on the ethmoid bone.
Coracoid Process
- The biceps brachii (short head) muscle inserts on the coracoid process of the scapula.
Annular Ligament
- The annular ligament primarily stabilizes the head of the radius against the ulna.
Sciatic Notches
- The ischial spine separates the lesser and greater sciatic notches.
Deltoid Ligament
- The deltoid ligament attaches the tibia to the calcaneus, talus, and navicular bones.
Ischial Tuberosity Origin
- The biceps femoris (long head) muscle originates from the ischial tuberosity.
Palmar Aponeurosis
- The palmar aponeurosis is continuous with the tendon of the palmaris longus muscle.
