What's the difference between muscle and perimysial?
Muscle
Definition:
(n.) An organ which, by its contraction, produces motion.
(n.) The contractile tissue of which muscles are largely made up.
(n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
(n.) See Mussel.

Perimysial
Definition:
(a.) Surrounding a muscle or muscles.
(a.) Of or pertaining to the perimysium.
Example Sentences:
(1) Muscle biopsy showed endo- and perimysial amyloid deposits but also inflammatory infiltrates.
(2) Deltoid muscle biopsy documented scattered basophilic regenerating myofibers and focal atrophic fibers with focal increases of endomysial connective tissue, small endomysial foci of inflammatory cells, and occasional perimysial, perivenular lymphocytic infiltrates.
(3) Perimysial collagen bundles and collagen strands increased both in number and thickness.
(4) A 15-year-old girl presented with rigid spine syndrome (RSS) associated with a myopathy of benign course, marked proliferation of perimysial and endomysial connective tissue, severe scoliosis, and progressive paralysis of upward and lateral gaze.
(5) Histochemical and ultrastructural studies of muscle biopsies at ages 2 and 3 months showed excessive mitochondria, lipid, and glycogen; a third biopsy at 6 months showed marked increase in perimysial fibrous and fat tissue.

(7) Mononuclear perimysial and epineurial infiltrates have been distinctive pathological findings.
(8) Eight of 13 cases examined by direct immunofluorescence demonstrated immunoglobulin deposition either within normal appearing vessels, within normal fibers, around or on the sarcoplasmic membrane, or within the perimysial connective tissue.
(9) These observations suggest that coiled perimysial fibers may act as a buffer to protect myocytes from damage under the effects of high cavity pressure.
(10) In two patients with peripheral neuropathy and one patient without overt neuropathy, denervation atrophy of muscle and perimysial and epimysial fibrosis were present.
(11) To evaluate the role of the coiled perimysial fibers under perturbed conditions, rat ventricles were filled with barium-gelatin under different pressures and fixed, and then the myocardium was impregnated with silver to visualize the connective tissue.
(12) On serial sections, combined deposits of IgG and Clq in perimysial arteries were seen in 38% of PMR.
(13) Calculations based on cross-sectional areas of fibers, changes in fiber configurations, and tensile moduli reported for collagen fibers of other tissues show that the potential tensile strength of the network of coiled perimysial fibers is sufficient to contribute significantly to the mechanical properties of papillary muscle.
