I.Types of muscle A.SKELETAL muscles attach to the skeleton. They function in movement and maintenance of posture. 1.They can be long (up to 30 cm). 2.They.
MECHANICAL PROPERTIES OF SKELETAL MUSCLE. Motor Unit A motor unit consists of a somatic motor neuron plus all the skeletal muscle fibers it stimulates.

Muscles & Muscle Tissue A. Functions 1. provide energy for movement 2. maintain posture 3. thermogenesis 4. maintain hollow organ volume.
Motor Systems. Motor Unit Motoneuron + muscle fibers it innervates Range in size from a few muscle fibers (e.g. extraocular muscles) To hundreds of.
Fibers: composed of myofibrils Myofibrils composed of protein filaments: 1.Myosin: thick filaments 2.Actin: thin filaments.
