The Musculoskeletal System
The human musculoskeletal system (also known as the locomotor system) is an organ system that gives humans and animals the ability to move using the muscular and skeletal systems. The musculoskeletal system provides form, stability, and movement to the human and animal body. It is made up of the body's bones (the skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue (the tissue that supports and binds tissues and organs together). The musculoskeletal system's primary functions include supporting the body, allowing motion, and protecting vital organs. The skeletal portion of the system serves as the main storage system for calcium and phosphorus and contains critical components of the hematopoietic system.
This system describes how bones are connected to other bones and muscle fibers via connective tissue such as tendons and ligaments. The bones provide the stability to a body in analogy to iron rods in concrete construction. Muscles keep bones in place and also play a role in movement of the bones. To allow motion different bones are connected by joints. Cartilage prevents the bone ends from rubbing directly on to each other. Muscles contract (bunch up) and extend (stretch) to move the bone attached at the joint.
There are, however, diseases and disorders that may adversely affect the function and overall effectiveness of the system. These diseases can be difficult to diagnose due to the close relation of the musculoskeletal system to other internal systems. The musculoskeletal system refers to the system having its muscles attached to an internal skeletal system and is necessary for humans to move to a more favorable position.
The Skeletal System serves many important functions; it provides the shape and form for our bodies in addition to supporting, protecting, allowing bodily movement, producing blood for the body, and storing minerals. The number of bones in the human skeletal system is a controversial topic. Humans are born with about 300 to 350 bones, however, many bones fuse together between birth and maturity. As a result an average adult skeleton consists of 208 bones. The number of bones varies according to the method used to derive the count. While some consider certain structures to be a single bone with multiple parts, others may see it as a single part with multiple bones. There are five general classifications of bones. These are Long bones, Short bones, Flat bones, Irregular bones, and Sesamoid bones. The human skeleton is composed of both fused and individual bones supported by ligaments, tendons, muscles and cartilage. It is a complex structure with two distinct divisions. These are the axial skeleton and the appendicular skeleton.
There are three types of muscles - cardiac, skeletal, and smooth. Smooth muscles are used to control the flow of substances within the lumens of hollow organs, and are not consciously controlled. Skeletal and cardiac muscles have striations that are visible under a microscope due to the components within their cells. Only skeletal and smooth muscles are part of the musculoskeletal system and only the skeletal muscles can move the body. Cardiac muscles are found in the heart and are used only to circulate blood; like the smooth muscles, these muscles are not under conscious control. Skeletal muscles are attached to bones and arranged in opposing groups around joints. Muscles are innervated, to communicate nervous energy to, by nerves, which conduct electrical currents from the central nervous system and cause the muscles to contract. 
Joints:
Human synovial joint compositionJoints are structures that connect individual bones and may allow bones to move against each other to cause movement. There are two divisions of joints, diarthroses which allow extensive mobility between two or more articular heads, and false joints or synarthroses, joints that are immovable, that allow little or no movement and are predominantly fibrous. Synovial joints, joints that are not directly joined, are lubricated by a solution called synovia that is produced by the synovial membranes. This fluid lowers the friction between the articular surfaces and is kept within an articular capsule, binding the joint with its taut tissue.
Tendons:
A tendon is a tough, flexible band of fibrous connective tissue that connects muscles to bones. Muscles gradually become tendon as the cells become closer to the origins and insertions on bones, eventually becoming solid bands of tendon that merge into the periosteum of individual bones. As muscles contract, tendons transmit the forces to the rigid bones, pulling on them and causing movement.
Ligaments:
A ligament is a small band of dense, white, fibrous elastic tissue. Ligaments connect the ends of bones together in order to form a joint. Most ligaments limit dislocation, or prevent certain movements that may cause breaks. Since they are only elastic they increasingly lengthen when under pressure. When this occurs the ligament may be susceptible to break resulting in an unstable joint.Ligaments may also restrict some actions: movements such as hyperextension and hyperflexion are restricted by ligaments to an extent. Also ligaments prevent certain directional movement.
Bursa:
A bursa is a small fluid-filled sac made of white fibrous tissue and lined with synovial membrane. Bursa may also be formed by a synovial membrane that extends outside of the join capsule. It provides a cushion between bones and tendons and/or muscles around a joint; bursa are filled with synovial fluid and are found around almost every major joint of the body.
This Medical Terminology Cache will require that you find words by their definitions and use the letter specified as a number in the coordinates which will be thus for this cache:
N 37° 39. ABC
W 122° 03. XYZ
To get the letter to convert into a number, use the following rules:
1. letters A through I are 1 through 9. (simple, right?)
2. letters J through Z: take the number value, add the two digits, like a checksum.
For J and S: ignore the 1 in the 10, use ZERO.
(example: J is 0, K is 2, L is 3…R is 9, S is 0, T is 2, U is 3…).
3. The only letter that will yield a 1 is A, remember this!
I will provide six definitions, you will need to figure out what word it is and what number the specified letter corresponds to, then plug it into the coordinates. The medical terms used come primarily from Latin and Greek. For example, cardiomyopathy is from Greek and the three parts mean “heart” “muscle” “disease”. Have fun and learn some new terms! Then go get that cache!
Order is: Letter in coordinates, Letter in word, Definition
A: letter 6: the most distal bone of the vertebral column
B: letter 2: inflammation of the bones of the fingers or toes
C: letter 4: surgical excision of a rib
X: letter 2: prime mover of jaw closure, elevates mandible, “chewer”
Y: letter 3: long thin superficial muscle of medial thigh
Z: letter 8: short triangular muscle near elbow, abducts ulna with forearm pronation
Cache is a medium-sized jar with camo, in view of what appears to be a new bridge that might be going in soon to cross the creek. Your back will be turned to the trail while searching for the cache, careful with muggles. Please return natural camo to keep it hidden!
