#13. The Broken bone described by the red arrows is the Fibula

#14. The red string is around the Gluteus Medius muscle. An extremely nice dissection !Note Origin = posterior surface of iliac bone and insertion is the Greater Trochanter. Action = medial rotation and abduction of Femur.

#15. The red string is around the Subscapularis muscle. Note that the origin is Subscapular fossa and Insertion = Lesser Tubercle. Action = Medial or inward rotation of Humerus at shoulder.

#16. Coracoid process

#17. Transversus Abdominis. Note the fibers are horizontal across abdomen. External and internal oblique muscle fibers pass obliquely across abdomen.

#18. Medial Malleolus (of Tibia). Note Tibialis Posterior, Flexor Digitorum Longus passing deep and using the Medial Malleolus as a pulley.

#19. A view from inside the Thorax of the internal surface of the Thoracic Wall. This is the Internal Intercosal Muscle. Note it is deeper than the External Intercostal muscle

#20. The string is around the Adductor Brevis Muscle. The Brevis is located between Adductor Longus and Adductor Magnus muscles.

#21. Crista Galli (Crest of the Rooster. A projection of the Ethmoid bone in the Cribriform Plate. We will see later in the course that this is an attachment site for the Dura Mater (A Protective covering of the Brain)

#22. Levator Scapulae muscle. This muscle Originates on the Transverse processes of Cervical vertebrae and Inserts on the Scapula. It acts to elevate the Scapula.

#23. The blue mark describes the Pubic Tubercle. This is an attachment for the Inguinal Ligament which also attaches on the Anterior Superior Iliac Spine.

#24. The Red marks describe the Vomer

#25. The painted area is the Acetabulum (Vinegar or Acetic Acid Cup. It is the cup that recieves the Head of the Femur to form the Hip Joint.

#26. The red string makes a circle to describe the Internal Acoustic Meatus (of the Temporal Bone)

#27. Quadratus Lumborum muscles. Origin is Transverse Processes of Lumbar vertebrae. Insertion is Iliac crest. Function is lateral flexion of vertebrae.

#28. Extra credit.Arrows describe an Intervertebral disc. AND it is composed of Fibrocartilage.

#29. Extra-CreditThe red origin (inferior angle scapula) and green insertion (Lesser Tubercle) are attachment sites for TeresMajor Muscle AND its actions are: Extension, Adduction, OR Medial Rotation of Humerus at Shoulder.

#30. Extra-CreditInside the bag was an Os Coxae(pubic, ischium & pubis).It was the Right on on Monday and Wednesday. It was the left one on Tuesday and Thursday.

#31. Extra-CreditWhat was missing from this structure ?C1 (atlas), C2 (axis), Dens or Odontoid process, L5, ANDTransverse Processes

#32. Pedicle (between body and transverse process of vertebra

#33. L is the Teres Major Muscle (from inferior angle of Scapula to Greater Tubercle of Humerus.

#34. The string is around the Short-Head of Biceps Femoris (Ischial tuberosity to Linea Aspera (of Femur).

#35. A beautiful tag of Serratus Anterior Muscle. Origin = rib, Insertion is Medial border of Scapula. It functions to hold the Scapula to the ribs.

#36. The string is around the Tibialis Anterior muscle. Note the Tibial and Fibula. The tagged muscle is therefore in the Anterior Compartment of the Leg. It is an anterior muscle with a surface against the tibia.

#37. This bone is the Incus. It is an ossicle from the middle ear. It articulates with both the Malleus and Stapes.

#38. The color describes the Intermediate Cuneiform Bone.

#39. The blue color describes the Capitulum (little head of the Humerus)

#40. The very end of the string encircles the Ischial Spine.

#41. The very end of the string encircles the Lesser Trochanter.Note that this is the insertion for the Iliopsoas tendon.

#42. The red string encircles the Trapezoid bone

#43. The string is around the Coracobrachialis muscle. Origin is Coracoid process of Scapula. Insertion is mid-Humerus.

#44. The Red string and wire pass into the Jugular Foramen. Note also that the Sigmoid Fossa of Posterior Cranial Fossa leads to the Jugular Foramen. This is the venous drainage for the brain.

#45. A tags Extensor Pollicus Longer, B tags the Extensor Pollicus Brevis.

#46. The green wire passes through the Foramen Spinosum. This hole is for a small artery to pass to and supply blood to the Dura Matter.

#47. This fibrous articulation is the Coronal Suture. It is named because it is in the coronal plane.

#48. This tissue has single centrally located nucleus. It is striated and branched. It is Cardiac Muscle or Myocardium.

#49. This tissue is bone. The arrows describe the Haversion Canals.

#50. This tissue Elastic Cartilage. Note the chondrocytes are the major cells and there

#51. This tissue Dense Regular Connective Tissue. The primary cell type is the

#52. This tissue is PseudoStratified Columnar Ciliated Epithelium. Note that it appears as though there are Stratified cells. This is because there are Simple Columnar cells of different heights. This epithelium will be found later in the course in the Respiratory System. This epithelium also has Goblet cells to produce Mucus. Particles inspired will get trapped in the mucus. The cilia move the mucus up into the mouth for disposal.

#53. The arrows describe Simple Cuboidal Epithelium. We will see this again in the

#54. This tissue is Transitional Epithelium. Note that it is stratified and the apical surface has many examples of Round or Umbrella cells. This is a sample from an empty bladder.
