Types/Stages of Muscle Contractions
What was the example provided in the lecture of isometric contractions?
a plank
agonist
Definition of Anatomy and Physiology
anatomy: the study of body parts
physiology: the study of the function of body parts
In the stages of muscular contractions calcium is connected to actin which leads to sarcomere _______ or muscle contraction ?
shortening
What is the purpose of Synergist?
helps primary mover do a certain action
What are the planes of the body?
sagittal plane, median plane (midsagittal), coronal/frontal plane, and transverse plane (cross section)
What's an Isometric Contraction?
What are the types of muscle fibers?
fast twitch fibers (IIx), slow twitch fibers (I), fast twitch (IIa)
What are the types of bones in our body?
long bones, short bones, flat bones, irregular bones, sesamoid bones
What is the difference between isometric and isotonic?
isometric contractions: the muscle is unable to shorten. Isotonic contractions: muscle shortens and lengthens.
What are the types of muscle actions?
Prime Mover/agonist, antagonist, synergist, neutralizer, fixator/stabilizer
rotation, circumduction, protraction, retraction, elevation, depression, and excursion
What is the first stage of muscular contractions?
a signal from motor neuron moves toward the neuromuscular junction
Why is neutralizers important for the human body?
It helps stabilize the muscles and the effect of a movement caused by another muscle
What are the different joint movements and what they mean?
abduction (away from midline), adduction (towards midline), dorsiflextion (towards shin), plantar flextion (away from shin), eversion (turning plantar surface of foot laterally), Inversion (turning plantar surface of foot medially), Supination (face/palm up), Pronation (face/palm down)
