muscle globin

The prefix "myo-" means "muslce-related." Myoglobin, also called "myohemoglobin" (also spelled "myohaemoglobin") is a type of protein that is found in muscles. It is defined as follows by the American Heritage Dictionary:

"A single-chain, iron-containing protein found in muscle fibers, structurally similar to a single subunit of hemoglobin and having a higher affinity for oxygen than hemoglobin of the blood."

Webster's Medical Dictionary defines it as follows:

"A red iron-containing protein pigment in muscles that is similar to hemoglobin but differs in the globin portion of its molecule, in the smaller size of its molecule (as in the mammalian heart muscle which has only one fourth the molecular weight of the hemoglobin in the blood of the same animal), in its greater tendency to combine with oxygen, and in its absorption of light at longer wavelengths."

I hope this addresses your question.
