Skeletal System
The skull, vertebrae, and ribs.
What is the axial skeleton?
Connects bone to bone.
What is a ligament?
What are fibrous joints?
The three types of muscle tissue
What are smooth, skeletal, and cardiac?
What is myelin?
The position of the sternum relative to the patella.
What is superior?
Connects muscle to bone.
What is a tendon?
Slightly moveable, such as the pubic symphysis.
What are cartilaginous joints?
Ability of a muscle to lengthen.
What is extensibility?
Neurotransmitter responsible for muscle contraction.
What is acetylcholine?
Responsible for blood cell production in bone.
What is red marrow?
Provides shock absorption and cushion at joints.
What is cartilage?
Freely moveable joints such as the shoulder or elbow.
What are synovial joints?
A contraction where the length of the muscle stays the same under tension.
What is isometric?
One motor neuron and all the muscle fibers it innervates.
What is a motor neuron?
Feature of the bone that stores energy.
What is yellow marrow?
Connective tissue that directly supports muscle tissue.
What is fascia?
A measurement of mobility at a joint, measured in degrees.
What is range of motion?
Two molecules found on actin.
What are troponin and tropomyosin?
What is the all-or-none principle?
3 functions of the skeletal system.
What are:
Protection of vital organs, attachment for muscles, support and maintain posture, production of blood cells, energy storage, storage and release of minerals.
The layer of fascia that becomes the tendon.
What is the epimysium?
The six types of synovial joints.
What are: ball and socket, condyloid, hinge, gliding, pivot, and saddle joints.
The reflex that occurs when the agonist contacts and the antagonist relaxes to allow movement.
What is reciprocal inhibition?
Motor unit with high fatigue resistance and low force production.
What are Type 1?
