Chapter 2: Muscular System Flashcards
Muscular system
The full collection of all of the muscles in the human body.
Epimysium
This is the layer of muscular connective tissue on the outside.
Perimysium
This is the muscular connective tissue in the middle that encompasses the muscle fascicle
Endomysium
The deepest layer of the muscular connective tissue that covers muscle fibers.
Tendons
Connect skeletal muscles to the bone with a band of white, inelastic, dense and tough band of tissue.
Sarcomere
This is the functional unit of a muscle that produces contractions. It is comprised of actin and myosin. This is the repeating section of a muscle
Neural Activation
his is the process of nervous system activation of a muscle fiber by the means of the neuromuscular junction
Motor unit
The motor neuron as well as all of the muscle fiber that it innervates.
Neurotransmitters
These are small chemical messengers that are able to cross the neuromuscular synapse (junction) in order to transmit these and electrical impulses from the nerve to the muscle.
