1
What systems make up the Human Movement System
Nervous, Muscular, and Skeletal
2
What system is known as the communication system of the body?
Nervous system- where all movement begins
3
What are the 2 subsystems of the nervous system
CNS and PNS
4
What does the CNS consist of
Brain and Spinal cord
5
Which of the nervous systems subsystems is the primary decision maker
CNS
6
What does the PNS consist of
Nerves from the CNS to the entire body
7
What does the PNS do
Send messages to CNS. Carries out actions from the CNS to the effector sites.
8
What are the 3 types of neurons
Sensory (afferent),interneurons, motor (efferent) neurons
9
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
10
What do interneurons do?
Transmit nerve impulses from one neuron to another.
Transmits messages from sensory neurons to the motor neurons
11
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
12
Name the 3 types of mechanoreceptors
Golgi Tendon organs
Muscle spindles
Joint receptors
13
Which receptor is responsible for sensing tension in muscles and connective tissue and forces muscle to relax
Golgi tendon Organ
14
Which receptor is responsible for sensing length in the muscle and forces the muscle to contract when stimulated?
Muscle spindles
15
Which receptor is responsible for sensing motion, acceleration, and deceleration in the joints. It protects the joints from a compromising situation
Joint receptors
16
Which system is compromised of muscles that work to move and stabilize the body
Muscular system
17
The muscular system is comprised of skeletal muscle tissue whose main function is what
contract on bone to create movement on joints
18
Primary mover of the joint (usually larger muscle)
Agonist
19
Opposing muscle of the prime mover. Decelerates the movement the agonist is producing
Antagonist
20
Lends assistance to the prime mover. Will start to take over for a weak prime mover
Synergist
21
Stabilizes the body and prevents unwanted movements
Stabilizers
22
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
23
During an overhead press name the following:
Agonist
Antagonist
Synergist
Stabilizer
Agonist: Deltoid
antagonist: Latissimus dorsi
Synergist:Triceps
Stabilizer: Rotator cuff
24
During a squat, name the Agonist, Antagonist, Synergist, and Stabilizer
Agonist: Glutes
Antagonists: Psoas
Synergist: Hamstrings
Stabilizers: Transverse Abs
25
During a row, name the Agonist, antagonist, synergist, and stabilizer muscles
Agonist: Lat dorsi
Antagonist: Pectoralis major
Synergist:Posterior deltoid and biceps
Stabilizer: Rotator cuff
26
Which system is responsible for support, protection, and allowing movement to occur
Skeletal system
27
What are the two functions of the skeletal system
LEVERAGE for our muscles
SUPPORT that directly affects our posture
28
Joint motion
arthokinematics
29
Rolling bone ex
Squat. Femoral condyles roll over tibial condyles
