Q

Fluid filled joint with a distictive oval shape.
It is a synovial joint.
Characterized by presence of a fluid-containing joint capsule, which lubricates the surface of adjacent bones in the joint.

17
Q

Facts about Coronal Suture

A

These sutures extend from temple to temple.
They do not form a straight line.
Bones fit tightly together like puzzle pieces.
Has no synovial fluid.

18
Q

Thin, delicate layer of connective tissue that surrounds individual muscle fibers.
Contains reticular fibers(contain collagen), blood vessels, capillaries, arteries, veins,and nerves that create a mesh-like network of vessels.

A

Endomysium

19
Q

Outermost layer of dense connective tissue surrounding muscles.
Primary Function-Combine with other muscular connective tissue to form a thick, collagenous cord of tissue known as-tendon

A

Epimysium

20
Q

A membrane that protects and supports groups of fibers within the skeletal muscle.
Responsible For: shaping @ organizing the muscle fibers @transmitting forces within the muscle.
Made of collagen @ elastin fibers.
Collagen fibers give tissue strength.
The elastin promotes elasticity. This holds the structure together @ allows fibers to move easily against one another.

A

Perimusium

21
Q

One of the bones that makes up the skull.
A spongy type of bone with light bony plates.
Situated between nasal cavity @ brain cavity, and makes up the nasal cavity roof, part of nasal cavity walls, part of bony orbits around the eyes, part of the floor of cranium.

A

Ethmoid Bone

22
Q

Located in pairs at the rear of each vertebrae.
Helps link adjoining vertebrae.
Known as Z-joints
Allow free movement of the spine.
They limit range of motion to protect the discs.

A

Facet Joints

23
Q

Longest, thickest @ strongest bone in body
Runs from pelvis to top of knee.
Gives support to entire body
Helps body contend with gravity.
Plays role in standing, walking, running @ jumping.

A

Femur

24
Q

Calf Bone
Smallest of 2 bones that run between knee and ankle
Bone is slender and not weight bearing

A

Fibula

25
Q

Shin Bone
Larger of 2 bones located between knee and ankle.
Considered to be strongest weight bearing bone in the body.
Triangular inner shape
Ridge running down front of leg-not covered by muscle

A

Tibia

26
Q

This bone is slightly different in men and women.
Men-vertically straight
Women-Slants down and slightly outward because women have wider hips than men

A

Tibia

27
Q

More likely to break than any other bone

A

Tibia

28
Q

Condition associated with the Tibia

A

Shin Splints

29
Q

Movement of joints, tendons and muscles beyond their normal limit.
May cause injury. Most commonly affected-knees and elbows.
Can cause joint pain, swelling, or immobility

A

Hyperextension

30
Q

Muscle running between the cheek bone and the lower jawbone.
2 on each side of skull, very strong
The mandibular nerve supplies the muscle with nerve impulses which cause it to contract raising and lowering the jaw when chewing or speaking.

A

Masseter Muscle

31
Q

Remaining in place. Not capable of movement or being moved.

A

Immobility

32
Q

The rotation of the forearm so that the palm faces posteriorly in relation to the anatomical position.

A

Pronation

In pronation the radius and ulna cross

33
Q

Rotation of the forearm so that the palm faces anteriorly in relation to the anatomical position.

A

Supination

In supination the radius and ulna are parallel

34
Q

Short bones which make up the foot

A

Tarsels

35
Q

The sac enclosing a joint. Made of outer fibrous articular capsule @ inner synovial membrane

A

Joint Cavity

36
Q

A muscle located in the facial region.
Begins at bridge of nose @ inserts into the frontal bone, between eyebrows.
Helps pull down skin between eyebrows.
Also aids in movement that allows flaring of the nostrils @ facial expression-show anger
Has a bit of pyramid shape
Primary Function-Provides protection to eyes from glare of sun

A

Procerus

37
Q

Strap-like muscle runs along lower half of body, from pubic bone to shaft of femur.
Linked to movement of thigh @ knee.
When referring to a pulled groin this muscle is involved

A

38
Q

This muscle can be used in a wide range of reconstructive surgeries. (ex: to cover wounds)

A

Gracilis Muscle
