Origin/Insertion
This point of a muscle attaches to the bone that is the most stationary
What is the origin?
This muscle is responsible for abduction of the shoulder
What is the deltoid (lateral head)?
This plane divides the body into front and back sections
What is the sagittal plane?
The most superior region of the spine is this
What is the cervical region?
These are the types of muscle contractions
What are concentric, eccentric, and isometric contractions?
This muscle inserts on the posterior surface of the calcaneus
What is the gastrocnemius?
This muscle group acts as a stabilizer and synergist to the shoulder
What is the rotator cuff?
This connects skeletal muscle to bone
What is a tendon?
This connects bone to bone
What is a ligament?
This consists of a motor neuron, an axon, and muscle fibres
What is the motor unit?
This muscle originates on the infraglenoid tubercle of the scapula, and the posterior surface of the humerus
What is the tricep brachii?
This muscle allows for knee extension
What is the Quadriceps (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius)?
This muscle is the antagonist to the bicep brachii
What is the tricep brachii?
The hip is this type of joint

This is where the nerves and muscles meet
What is the neuromuscular junction?
These four muscles insert on the tibial tuberosity
What are the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedialis (Quadriceps)?
This muscle allows for internal rotation, adduction, and flexion of the arm
What is the pectoralis major?
This muscle tissue is what the heart is made up of
What is cardiac muscle?
The skeletal system is divided into these two main parts
What are the axial and appendicular skeletons?
These are also known as the thick and thick filaments
