bones and muscles 6 Flashcards
Most of the skeleton of an infant made up of ____________
Cartilage
The principal minerals stored by bones are________and_____________
- calcium 2. phospherus
A broken bone that is splintered or crushed is _____________
Comminuted Fracture
A broken bone with an open wound is _________________
Compound Fracture
An incomplete break of a soft bone (usually a childs) is a _________________
Greenstick Fracture
A _____________fracture does not move any part of the bone out of place
Simple
Lateral, sideways curvature of the spine
Scoliosis
Outward curvature of the thoracic spine (hunchback) is called___________
Kyphosis
Inward curvature of the spine is ___________
Lordosis (extreme form swayback)
Muscles pull, never________
Push
An overcoat that surrounds the WHOLE MUSCLE
Epimysium
Covering of EACH MUSCLE FIBER
Endomysium
Connective tissue fibers that divide the skeleton muscle into a series of compartments, each contain a BUNDLE OF MUSCLE FIBERS
Perimysium
Bundle of muscle fibers
Fascicles
State of sustained, partial contraction of muscles that is necessary to maintain posture
Muscle Tone
3 Types of Muscular Tissue
- SKELETAL (Voluntary)
- SMOOTH (Involuntary)
(Respitation, Urination, Digestion) - CARDIAC
Characteristics of Muscle
- Excitability-ability to respond to stimuli
- Contractility-able to shorten
- Extensibility-able to stretch
- Elasticity-ability to return to original shape and length
Trauma to joints with pain, swelling, and injury to ligaments
Sprain
Muscle injury involving overstretching of a muscle with pain and swelling. Less severe than a sprain
Strain
Members of a group of muscles working together to produce a movement
Synergist
Muscle that plays a major role in accomplishing the movement
Prime Mover
Palms face upward
Supination
Palms face downward
Pronation
Muscle above and near the ear
Temporal
Lack of ATP can cause a muscle _________
Cramp
Attaches bone to bone
Ligament
Connects muscle to bone
Tendon
Place where 2 bones come together
joint
2 Kinds of Joints
- Immovable (skull) 2. Movable
4 Types of Movable Joints
- Hinge (knee, elbow)
- Pivot (Neck)
- Ball + Socket (shoulder, hip)
- Gliding (wrist, ankle)
Structural change in muscle tone and inability to move muscle. Muscle is in a permanent state of contraction
Contracture
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.
