Musculoskeletal System
The musculoskeletal system, also called the locomotor system, is an organ system that gives humans and animals the ability to move using their muscular and skeletal systems. It provides stability, form, support, and movement to the body. The skeleton is composed of bones (skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system is subdivided into two broad systems, such as the muscular system and the skeletal system.
Skeletal structure
The skeletal system is the core framework of the human body. The skeletal structure comprises bones and connective tissue, including cartilage, ligaments, and tendons. The skeletal structure of our body acts as a support structure. It maintains the body's shape and is responsible for its movement, blood cell formation, protection of organs, and mineral storage. The skeletal system is referred to as the musculoskeletal system.

Mystery Organism Identification
You will be given a pure culture of one of three organisms. Your assignment is to identify which of
the three possibilities is in your culture tube. To do this, you will use two different types of media:
Mannitol Salt Agar and MacConkey's Agar. Complete the table below by predicting the reactions
of each organism on each medium (Growth or no growth? If you expect growth, what color should
it be?). Do this before coming to lab on the due date. The information about each organism below
and the information found in the theory sections for the labs should help you make your
predictions. If you complete this table correctly, it will be a big help to you while you try to identify
MSA
MAC
your mystery organism!

Escherichia coli
E. coli is a Gram-negative facultative anaerobe. It is part of the normal gut flora of humans and
of the Combination Media to identify the unknown organism in your original
microtube. Which of the three organisms listed in the Combination Media matches the
growth patterns you observed on the MSA and MAC agar plates above?
other animals, where it helps in digestion and vitamin synthesis. As a member of the family
Enterobacteriacae, it exhibits both respiratory and fermentative metabolism. E. coli is capable of
fermenting several sugars including glucose, mannitol, lactose, sorbitol, arabinose, and maltose.
Proteus mirabilis
P. mirabilis is a Gram-negative facultative anaerobic rod. It is also a member of the family
Enterobacteriacae and is part of the normal gut flora in up to half of the human population. P.
mirabilis is not as diverse as E. coli in terms of the sugars it can utilize for fermentation (unlike E.
coli, P. mirabilis cannot ferment mannitol or lactose), it is able to hydrolyze urea, a capability that
E. coli does not possess.
Staphylococcus aureus
S. aureus is a Gram-positive, facultative anaerobic coccus. Although it is a potential pathogen, a
significant proportion of the general population (-20-30%) harbors S. aureus on the skin and nasal
mucosa, where it is able to live due to its osmotolerance (tolerance of high salt environments).
Substrates for fermentation include glucose and mannitol. S. aureus is distinguished from organisms
like Enterococcus faecalis by its production of catalase.

Expert Solution
Step 1
In microbiology, one of the most important components is the medium. Microorganisms such as bacteria, fungus, and yeast can grow in it. It is used to isolate many types of bacteria in the laboratory.
