NAFC PERSONAL TRAINING EXAM QUESTIONS WITH 100%
CORRECT ANSWERS!!
Integumentary System
Skin, hair, nails, oil glands, and sweat glands.
Epidermis
The outermost layer of skin.
Hair (all over the body)
(on skin) Can sense insects on the skin before they bite.
(on the scalp) guards against heat, sunlight, physical trauma and heat loss.
(on eye) shield the eyes, and
(on the nose) hairs filter particles from entering the lungs.
Ossification
The process of new bone development.
Appendicular
The skeletal system associated with shoulders, arms, and legs.
MInerals
Stored in bones (where red blood cells are located)
Skeletal Muscles
Use bones as levers to move the different parts of the body.
Bones
Provide a hard framework that supports the body and cradles the soft organs.
Organs
Protected by bones (i.e rib cage)
Axial (Skeletal System)
Includes the bones from the head to the base of the spine.
Fascicules
Bundles of muscle fibers grouped together.
Myofibrils
A protein strand made up of contractile proteins.
Sarcomeres
The basic unit of the myofibril, which contains myosin and actin.
Myosin
(thick, dark protein) that contributes in the making of a sarcomere. myofilaments
Actin
(thin, light protein) that contributes in the making of a sarcomere. myofilaments
Cross Bridges
Projections extending from the myosin to the actin
Visceral muscle tissue
Smooth muscles found in the organs. An involuntary type of tissue because we do not
consciously contract our organ or digestive system functioning.
Cardiac muscle tissue
Type of tissue found in the heart. It is responsible for pumping blood through the body.
This pumping is, of course, done through involuntarily contracting.
