Internal force
connective-tissue
Name the 3 purposes of skeletal muscles

- supports soft tissue
What is muscle fascia (fibrous connective tissue)
Separates muscles and muscle groups
Provides shape to the arranged fibers it contains
Maintains intramuscular tension.
Three parts of the skeletal muscular architecture
Muscle fascia
Myofibrils
Myofilaments
Long cylinder like fibers (muscle cells)
Myofibrils
Proteins within Myofibrils that set the actions of muscle into motion
Myofilaments
Thick Myofilaments
Thin filaments
Myosin
Actin

Supraspinatus muscle
Increasing the length of the _____ will increse the difficulty of exercise
Resistance Arm
the ______ consists of a single motor neuron and all of the muscle fibers it innervates
motor unit
Causes trunk rotation and lateral flexion
external oblique
During an abdominal curl-up it is important that the pelvis remains tilted ____ during abdominal flexion due to the fact that the abdominals connect to the pelvis and not the femur
