For this assignment, using the OIA tables from the lab guide (NOT other resources as there are more muscles you don't need to know), LIST all the muscles that originate on the following bones:

a Scapula
b Humerus
c Vertebrae
d Os coxae (hip bones - ilium, ischium, pubis)
e Tibia

Final answer:

The scapula, humerus, vertebrae, os coxae (hip bones), and tibia are origins of various muscles like the gluteus maximus, gluteus medius, gluteus minimus, and the erector spinae group. The iliotibial tract also originates on the tibia.

Step-by-step explanation:

List of Muscles Originating on Specific Bones

According to your lab guide and the OIA tables, we have several muscles that originate on different bones of the body. Below is the summarized list of muscles originating from the specified bones:

Scapula

The scapula serves as the origin for multiple muscles, although your question doesn't provide specific names, commonly muscles like the deltoid, supraspinatus, infraspinatus, teres major, and teres minor originate here.

Humerus

Similarly, the humerus bone is the origin for muscles like the biceps brachii, brachialis, and triceps brachii.

Vertebrae

The erector spinae group, consisting of the iliocostalis, longissimus, and spinalis muscles, originates along the vertebrae.

Os coxae (hip bones)

On the hip bone, which includes the ilium, ischium, and pubis, several muscles originate such as the iliopsoas group (formed by iliacus and psoas major muscles), and muscles of the gluteal region like the gluteus maximus, gluteus medius, and gluteus minimus.

Tibia

The iliotibial tract muscle originating at the tibia is composed of the gluteus maximus and connective tissues of the tensor fasciae latae.
