25
Which incisor is the lateral, and which is the central? Are these maxillary or mandibular
26
How can you tell the difference between an incisor and a canine?
Incisors have a flat, thin, blade-like crown with a sharp incisal edge used for cutting. Their crowns are generally rectangular in outline, with a straight or slightly curved incisal margin, and they lack pronounced cusps. The root is usually single, straight, and relatively short compared to canines. Canines are more conical and robust, with a single prominent cusp at the crown’s tip, designed for tearing. The crown tapers smoothly to this pointed cusp, giving it a triangular profile from the side. Canines also have the longest roots in the dentition, which are thick, rounded, and often slightly curved (distally).
27
What is the first step you should use to determine what kind of tooth you are looking at?
28
What is the second step you should use to determine what kind of tooth you are looking at?
29
What is the third step you should use to determine what kind of tooth you are looking at?
30
What is the third step you should use to determine what kind of tooth you are looking at?
31
What is the fourth step you should use to determine what kind of tooth you are looking at?
32
How do you use conids, cones, Y5, 4+, trigone and trigon and talon to differentiate all the different molars
33
How do you determine the buccal side of the upper and lower molars
34
Once you determine the buccal side of the molars, how do you determine the mesial and distal sides?
35
This is the upper molars btw

What vertebrae is this
1st cervical
40
What vertebrae is this
2nd cervical
41
this is the 2nd cervical vertebrae

46
What ribs are these
Left 2nd , Right 1st
47
What rib is this? How do you know?
The rib is a right-side central ribs. The costal groove can be seen and is inferior, helping indicate the right-sidedness. It is a central rib, known because it has two facets, which is not seen in the 11th and 12th ribs. The second rib is flatter and has a rough patch on the serratus anterior.
48
49
How can you determine which side the first rib belongs to?
The subclavian groove is on the superior portion of the rib
50
You have a rib with only one articular facet on the vertebral side, but also a facet on the tubercle, what rib is it going to be?
The 10th rib
51
52
What are the two points on the scapula that the trapezius inserts?
Scapular spine and acromion process
53
What are the two insertion points of the biceps brachii?
the long head arises from the supraglenoid tubercle, and the short head originates from the coracoid process. both on the scapula
54
What is the OIF of supraspinatus
55
What is the OIF of infraspinatus
56
What is the OIF of subscapularis
57
What is the OIF of teres minor

| This is the radius btw

67
What are the insertions for gluteus maximums, medius and minimus
Minimus and Medius: Greater trochanter of the femur Maximums: Gluteal tuberosity
68
Which side?
Right
69
70
71
72
73
Where do the patellar ligament and quadriceps femoris muscle insert?
The tibial tuberosity
74
75
What is the origin for the peroneus longus and peroneus brevis
Lateral surface of the fibula
76
What is the OI of gluteus maximums?
O: Back of ilium, sacrum, and coccyx I: Iliotibial tract and gluteal tuberosity of femur
77
What is the OI of gluteus medius?
O: Outer surface of ilium I: Lateral greater trochanter of femur
78
What is the OI of gluteus minimus?
O: Outer surface of ilium (below medius) I: Front of greater trochanter of femur
79
For the hand: * anterior = ____ * posterior = ____ * medial = ____ * lateral = ____
* anterior = palmer * posterior = dorsal * medial = ulnar * lateral = radial

How to distinguish between isolate metatarsals and metacarpals

82
Which bone is this and how would you side it?
Calcaneus. All of the facets face the medial side. You can also use the sustentaculum tali
83
What is this called and what bone is it on?
sustentaculum tali on the calcaneous
84
85
use the head and body to identify medial side
86
What bone is this and how would you side it?
so overall it is shaped like an arch, kinda like the bean in Chicago so you can tell top vs bottom. The bottom will have a tuberosity that sticks out to the side the most, that is the medial side. The concave facet is posterior Overall this is the right navicular
87
What bone is this and how would you side it?
This is the right cuboid. The superior surface is smooth, whereas inferior has a prominence. The posterior facet is concave. The medial surface has a facet, and the lateral surface has a tuberosity.
