Neuro and Fascial Connections Flashcards
(21 cards)
Reciprocal Inhibition
Reflex mechanism that coordinates the effort between agonist and antagonist muscles
Hypertonicity
Excessive muscle tension
Alpha Loop
Made up of alpha sensory neuron looped around central region of muscle spindle and alpha motor neuron that innervates extrafusal fibers. This loop is the reflex arc for the stretch reflex.
Gamma Loop
Made up of gamma sensory attached toward end of the spindles and the gamma motor neuron which innervates the intrafusal fibers.
Gamma Gain
Increased tension of the intrafusal fibers heightens the proprioceptors sensitivity to rate of lengthening.
Tensegrity
Tension between two opposing forces can be balanced to create structural integrity.
Fascial Layers
Pannicular – outermost layer surrounds body and is made up of mostly subcutaneous fat and superficial muscle
Axial – surrounds compartments in skeletal muscles as well as ligaments, tendons, and periosteum
Meningeal - surrounds brain and spinal cord
Visceral – holds organs together as well as parietal and peritoneal layers of serous membranes in ventral cavity.
Superficial Fascia
Includes the hyprodermis to connect to underlying structures and some superficial muscles
Deep Fascia
Combo of all other layers that surround muscle, bones, and organs.
Myofascial Train
connective tissue links between muscles, bones, and fascial membranes that provide a pathway for the mechanical communication of tension and compression throughout the body.
Viscoelasticity
Special collagen structure and organization allows tissues to extend and rebound. Collagen fibers consist of tropocollagen which is a special protein molecule that has a triple helix structure which gives this ability.
Thixotropy
allows for CT to move from a more gel like state to more liquid state. Thanks to water magnet called GAGs.
Piezoelectricity
When CT is subject to mechanical pressure it creates a small electrical charge which excites fibroblasts and inhibits fibroclasts.
Fascial plasticity
Something to be molded or changed. Neural plasticity is an example but fascia research shows its ability to be adaptive.
Fascia as sensory organ
Contains:
Golgi Receptors
Pacinian corpuscles
Ruffini corpuscles
Interstitial myofascial receptors (most abundant)
Proprioception
Persons sense of body position
Kinesthesia
Persons sense of movement
Type 1 Fibers
High density of mitochondria and myoglobin. Red in appearance and are slow twitch fibers
Type 2 Fibers
White or fast twitch fibers. Low in mitochondria and myoglobin
Postural Muscle
High endurance Ex. Erector spine and Iliopsoas
Phasic Muscle
Low endurance fast twitch Ex. biceps and hamstrings
