1. calcium 2. phospherus

3

Comminuted Fracture

4

A broken bone with an open wound is _________________

Compound Fracture

5

Greenstick Fracture

6

A _____________fracture does not move any part of the bone out of place

Simple

7

Lateral, sideways curvature of the spine

Scoliosis

8

Outward curvature of the thoracic spine (hunchback) is called___________

Kyphosis

9

Inward curvature of the spine is ___________

Lordosis (extreme form swayback)

10

Muscles pull, never________

Push

11

An overcoat that surrounds the WHOLE MUSCLE

Epimysium

12

Covering of EACH MUSCLE FIBER

Endomysium

13

Connective tissue fibers that divide the skeleton muscle into a series of compartments, each contain a BUNDLE OF MUSCLE FIBERS

Perimysium

14

Bundle of muscle fibers

Fascicles

15

State of sustained, partial contraction of muscles that is necessary to maintain posture

Muscle Tone

16

3 Types of Muscular Tissue

1. SKELETAL (Voluntary)
2. SMOOTH (Involuntary)
(Respitation, Urination, Digestion)
3. CARDIAC

17

Characteristics of Muscle

1. Excitability-ability to respond to stimuli
2. Contractility-able to shorten
3. Extensibility-able to stretch
4. Elasticity-ability to return to original shape and length

18

Trauma to joints with pain, swelling, and injury to ligaments

Sprain

19

Muscle injury involving overstretching of a muscle with pain and swelling. Less severe than a sprain

Strain

20

Members of a group of muscles working together to produce a movement

Synergist

21

Muscle that plays a major role in accomplishing the movement

Prime Mover

22

Palms face upward

Supination

23

Palms face downward

Pronation

24

Muscle above and near the ear

Temporal

25

Lack of ATP can cause a muscle _________

Cramp

26

Attaches bone to bone

Ligament

27

Connects muscle to bone

Tendon

28

Place where 2 bones come together

joint

29

2 Kinds of Joints

1. Immovable (skull) 2. Movable

30

4 Types of Movable Joints

1. Hinge (knee, elbow)
2. Pivot (Neck)
3. Ball + Socket (shoulder, hip)
4. Gliding (wrist, ankle)

31

Structural change in muscle tone and inability to move muscle. Muscle is in a permanent state of contraction

Contracture

32

Facts about the Platysma Muscle

Muscle of facial expression
Begins at the chest runs up over collarbone +strethes up along the sides of the neck to the chin.
Primary Function-To help move the lower lip + jaw downward or to the side.
The contraction of this muscle makes a variety of facial expressions such as: Smiling, Frowning, Grimacing.
Contributes to a condition known as double chin.
