Chapter 2 Flashcards
(46 cards)
What systems make up the Human Movement System
Nervous, Muscular, and Skeletal
What system is known as the communication system of the body?
Nervous system- where all movement begins
What are the 2 subsystems of the nervous system
CNS and PNS
What does the CNS consist of
Brain and Spinal cord
Which of the nervous systems subsystems is the primary decision maker
CNS
What does the PNS consist of
Nerves from the CNS to the entire body
What does the PNS do
Send messages to CNS. Carries out actions from the CNS to the effector sites.
What are the 3 types of neurons
Sensory (afferent),interneurons, motor (efferent) neurons
Which neurons transmit nerve impulses form effector sites to the brain and spinal cord. These send info from the environment up to the brain
Sensory neurons
What do interneurons do?
Transmit nerve impulses from one neuron to another.
Transmits messages from sensory neurons to the motor neurons
Which neurons transmit nerve impulses form the brain and spinal cord to effector sites. Sends messages from the brain to the body
Motor (efferent) neurons
Name the 3 types of mechanoreceptors
Golgi Tendon organs
Muscle spindles
Joint receptors
Which receptor is responsible for sensing tension in muscles and connective tissue and forces muscle to relax
Golgi tendon Organ
Which receptor is responsible for sensing length in the muscle and forces the muscle to contract when stimulated?
Muscle spindles
Which receptor is responsible for sensing motion, acceleration, and deceleration in the joints. It protects the joints from a compromising situation
Joint receptors
Which system is compromised of muscles that work to move and stabilize the body
Muscular system
The muscular system is comprised of skeletal muscle tissue whose main function is what
contract on bone to create movement on joints
Primary mover of the joint (usually larger muscle)
Agonist
Opposing muscle of the prime mover. Decelerates the movement the agonist is producing
Antagonist
Lends assistance to the prime mover. Will start to take over for a weak prime mover
Synergist
Stabilizes the body and prevents unwanted movements
Stabilizers
During a chest press, name the following: Agonist: Antagonist: Synergist: Stabilizer:
Agonist: Pectoralis major
Antagonist: Posterior deltoid
Synergist:Anterior deltoid and triceps
Stabilizer:Rotator cuff
During an overhead press name the following: Agonist Antagonist Synergist Stabilizer
Agonist: Deltoid
antagonist: Latissimus dorsi
Synergist:Triceps
Stabilizer: Rotator cuff
During a squat, name the Agonist, Antagonist, Synergist, and Stabilizer
Agonist: Glutes
Antagonists: Psoas
Synergist: Hamstrings
Stabilizers: Transverse Abs
