- foramen ovale - more oval shapped, medial and slightly inferior to foramen spinosum
- foramen spinosum - smaller and lateral to foramen ovale
- sella turcia - saddle
- hypophyseal fossa - part of sella turcia where “rider would sit”
4
Q
Parts of Ethmoid bone
A
- crista galli - shark fine at top of ethmoid bone
- perpendicular plate - vertical flat along midline
- superior and middle conchae - can only really see superior conch from posterior view. From face on it is the back part of the middle conchae. Middle conchae run parallel to perpendicular plate
- cribriform plate - plate around crista galli, has holes
- cribriform foramina - holes slightly lateral to cribriform plate
5
Q
Parts of Maxillae
A
- zygomatic process - process which fuses which zygomatic bone
- alveolar process - sockets for teeth
- palatine process - front part of the roof of the mouth.
6
Q
Parts of Mandible
A
- Mandibular body - chin part of mandible
- Mandibular ramus - angle part of mandible
- Mandibular condyle - condyle on posterior process (condylar process)
- Mandibular foramen - inside ramus
- coronoid process - process anterior to condylar process
- mental foramen - R and L foramen of “chin”
- alveolar process - sockets of teath
- mylohoid line - low ridge on internal side of mandibular body
7
Q
parts of palatine bones
A
- horizontal plate - back of the roof of your mouth,
8
Q
parts of zygomatic bones
A
- temporal process of zygomatic bone - part of zygomatic bone which connects to zygomatic process of temporal bone
9
Q
Parts of lacrimal bones
A
- lacrimal fossa - fossa in lacrimal bone
10
Q
Parts of Hyoid bone
A
- body - frontal part
- greater horns - part directed towards vertebrae behind lesser horn
- lesser horns - spin like perpendicular projection
11
Q
Features of a rib
A
- costal cartilage
- head
- tubercle (articular facet of the tubercle): tubercle, right before bend coming from head
- costal groove - short, shallow depression along the body of rib, inferior side
12
Q
Parts of Fibulae
A
- Head - Expanded proximal end. Attachment to tibia.
- Lateral malleolus - distal end of fibula, located on the outer side of the ankle. Bony prominence on the outer side of ankle. The fibula is basically a head, shaft and lateral malleolus.
It serves as an attachment point for muscles and ligaments involved in movement and stabilization of the ankle and foot. NOT weight bearing
attaches to tibia and talus bone of ankle
there is a medial malleolus on the tibia
13
Q
Parts of patellae
A
- apex - thin tapered distal edge. provides attachment for patella ligament. Pointier end
14
Q
Parts of Tibia
A
- Medial Condyle -> proximal head of tibia, medial side. Articulates with medial condyle of femur.
- Lateral Condyle -> proximal head of tibia, lateral side. Articulates with lateral condyle of femur.
- Intercondylar eminence -> protrusion between the two condyle. Small directly in the center.
- Tibial tuberosity -> bony prominence on the anterior (front) surface of the tibia, just below the knee joint. You can feel it.
- Anterior Crest / anterior border -> The anterior crest is a sharp, prominent ridge running down the anterior (front) surface of the tibia, extending from just below the tibial tuberosity to the distal end of the bone
- Fibular Notch -> The fibular notch is located on the lateral side of the distal end of the tibia. Gives space to fibula.
- Medial malleolus -> The medial malleolus is the bony prominence located at the distal end of the tibia, on the inner (medial) side of the ankle
15
Q
Parts of femur
A
- Head -> ball-like proximal end of the femur
- Fovea capitis -> The fovea capitis is a small, concave depression on the head of the femur
- Neck -> between head and greater torchanter
- Greater Trochanter -> large projection, lateral to head
- Lesser Trochanter -> smaller projection, a bit posterior and inferior to head.
- Intertrochanteric Line -> line between greater and lesser trochanter. Anterior side.
- Intertrochanteric crest -> crest between greater and lesser trochanter. Posterior side.
- Linea aspera -> rough ridge that travels the posterior aspect of the body of the femur
- Lateral epicondyle -> bump above lateral condyle
- medial epicondyle -> bump above medial condyle
- abductor tubercle -> directly above medial epicondyle. Looks like top of curve.
- lateral condyle
- medial condyle
- intercondylar fossa -> depression between condyle (lines up with intercondylar eminence of tibia). Posterior side
- patellar surface - > the patellar surface is on the anterior (front) side of the femur. It is the center of the articulating surface, while the intercondylar fossa is on the posterior (back) side of the femur.
epicondyle is a rounded bump that is smaller then the condyle and located on top or attached to the condyle
18
Q
Describe parts of pubis
A
- pubic symphysis - joint between pubis (cartilage / ligaments)
- inferior pubic ramus - directly inferior, other side of obturator foramen.
- superior pubic ramus - superior and lateral (near acetabulum). Bone changes angle
- pubic arch - arch created by pubis under pubic symphysis.
