||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Skeletal Muscle Organ? - correct answers✔✔1) ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Endomysium ||\\||\\




2) Perimysium
||\\||\\

,3) Epimysium
||\\||\\




4) Fascia. ||\\||\\




Endomysium - correct answers✔✔A thin sleeve of loose ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




connective tissue that surrounds each muscle fiber. ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




(Muscle fiber excitation occurs in the Endomysial tissue). ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Perimysium - correct answers✔✔A thicker connective ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




tissue sheath that wraps muscle fibers together in bundles
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




called Fascicles.
||\\||\\ ||\\||\\




Epimysium - correct answers✔✔Fibrous tissue sheath ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




that surrounds the entire muscle.
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Fascia - correct answers✔✔A sheet of connective tissues
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




that separate neighboring muscles from each other & the
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




subcutaneous tissue. Muscles are grouped in ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




compartments based off of these separations. ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\

,Fascicles are oriented in different ways which determine ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




______________________ - correct answers✔✔A ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




muscles strength & range of motion. ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Muscles are classified off of _______________ - correct
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




answers✔✔Fascicle orientation. ||\\||\\




Fusiform Muscles - correct answers✔✔Thick in the ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




middle and tapered at each end. Muscle strength is
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




proportional; very strong. (EX: Biceps) ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Parallel Muscles - correct answers✔✔Uniform width &
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




parallel fascicles. Can be either elongated or quadrilateral
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




& produce less force due to little amounts of muscle
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




fibers. (EX: Rectus Abdominis)
||\\||\\ ||\\||\\ ||\\||\\




Triangular (Convergent) Muscles - correct ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




answers✔✔Fan-Shaped; Broad as one end. Relatively ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




strong due to many muscle fibers. (EX: Pectoralis Major)
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\

, Pennate Muscles - correct answers✔✔Feather shaped; 3
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




types: Unipennate, Bipennate, & Multipennate.
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Unipennate Muscles - correct answers✔✔Fasciles run ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




obliquely from a tendon on one side only. (EX: Palmar||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Interosseous)


Bipennate Muscles - correct answers✔✔Fascicles run ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




obliquely on both sides from a central tendon. (EX: Rectus
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




Femoris)


Multipennate Muscles - correct answers✔✔Fascicles ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




converge as a single point; has the most force out of the 3
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




pennate muscles. (EX: Deltoid) ||\\||\\ ||\\||\\ ||\\||\\




Circular Muscles - correct answers✔✔Form rings around
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\




certain body openings; Sphincters.
