About This video!
Skeletal Muscles
The muscles that are attached to the skeleton and are associated with the movement of bones are called skeletal muscles. The skeletal muscles are consciously controlled and therefore, are called voluntary muscles. Skeletal muscles are also called striped or striated muscles because they show alternate light and dark bands, e.g., triceps and biceps. Generally, each end of the entire muscle is attached to bone by a bundle of collagen, non-elastic ibres, known as tendons.
Skeletal Muscle Fibre : Each muscle consists of muscle bundles, which are further composed of muscle ibres or cells. Each muscle ibre is a long cylindrical cell with multiple oval nuclei arranged just beneath its sarcolemma. Skeletal muscle ibres are huge cells. Their diameter is 10 - 100 mm.Sarcoplasm of the muscle ibre is similar to the cytoplasm of other cells but it contains usually large amount of stored glycogen and unique oxygen bonding protein myoglobin, a red pigment that stores oxygen.
When viewed in high magniication, each muscle ibre is seen to contain a large number of myoibrils 1-2 mm in diameter that run in parallel fashion and extend entire length of the cell. Bundles of these fibrils are enclosed by the muscle cell membrane or sarcolemma. The myofibrils consist of smaller contractile units called sarcomere. In each sarcomere a series of dark and light band are evident along the length of each myoibril. Each dark band is called A band, because it is anisotropic, i.e it can polarize visible light. The light band called I band is isotropic or non-polarizing. It gives the cell as a whole its striped appearance. Each A band has a lighter stripe in its mid section called H - zone

Endomysium: covering of muscle fibres.
Perimysium: covering of fasciculi or muscle bundle.
Epimysium: covering whole bundle of fasciculi.

Sir jo central lines yaa fir middle lines hai,,, wo imaginary hai yaa actual main usme hai?? Aur hum wo middle line kyun padhte hai??

[@AbdulZahid-ft6xh]

Good lacture sir thank you

[@kazigolamsarwaruzzal5335]

It"s Bangla version will be much more helpful to the Bangladeshi
learners. So, would you make It's Bangla version?

[@samandarkhan6237]

Good information.

[@ayaanashraf5353]

Ma shaa ALLAH keep it up sir💝

[@adinaalina9434]

Sir isotropic means polarized with light ..

[@tanzeelamasood7390]

✨✨Best lecture sir

[@foziabaloch1722]

Lil confusion..ain't the connective tissue layer covering the muscle epimysium? And perimyisium z dat covering of muscle bundle ?

[@adisoni]

True bro☺

[@ayeshamenahil930]

Yes

[@sharmikirangpk5493]

Yeah it's wrong

[@annakhan1687]

yes

[@Your_zoon]

Yes yes yes I was so confused about that thank u

[@hammadkvlogs2470]

Thanks you so much sir you make this topic much easier 💗💗♥️❤️

[@maazullah5052]

Sir ge the muscles covering layer called epimysium

[@zarakhan6308]

Awesome yarrr....thnk u soooo much sir..

[@Doctorgirl356]

Very help full 😊😊

Edopmysium is the covering layer of myocytes

[@lifewithzeemalkhan]

Waooooo Amazing sir ❤ ..... thank u soo much 😍

[@zeenatkhan3253]

Tnk u sir it's very nice lecture

[@Nasir.Iqbal_]

the epimysium comes first and perimysium comes later

[@habibswati5608]

Zabardast

[@ansvicky9363]

thanks

[@shortcircuit900]

very detailed explanation..❤️❤️❤️

[@faizanraza5730]

First time.....my pakistani bro....has done great conceptual clearity.....can u plz make us prepaer for ppsc

[@ALIACADEMYAR7]

Yes dear

[@nayabsadheer520]

Sir I can't find the leacture of topic Locomotion In Protectista and Invertebrate . Sir is the leacture is uploaded or not

[@syedhasan6738]

isotropic is nonpolarizing please clear this point anisotropic is polarizing

[@maazullah5052]

And perimysium the covering layer of fascicles

[@iqra-jahangir]

Sir...how calmodium regulate protein in muscle?

[@attaullahbaloch6390]

Sir ap great ho

[@boottafun9877]

😍🙇 thanks dear respected sir

[@fidahussain7724]

If 1 am not wrong the tissue covering the muscle bundles/fascicules is perimysium

[@ALIACADEMYAR7]

Yes

[@fidahussain7724]

But sir mujhe laga aap ne epimysium kaha hai shayad may be I got it wrong

[@urdupoetry2221]

Very nice

[@mairakhan1350]

Sir plx muscular system ka lecture upload krlo

Sir are mayofibrill and muscle fibre are same units

[@syedfaheem860]

Ossm sirrr

[@Hinafatima567]

Assalam o alaikum sir! Federal board ki book men likha hua he ke muscle ki outer layer ko epimysium or muscle bundle ki outer layer ko perimysium kehte hen
Please ye confusion clear kar den

[@fatimafaiz4844]

Amazing!!

[@amanrajpoot8653]

Most easiest method 👍

[@syedhasan6738]

muscle is covered my epimysium and the fascicles are surrounded by perimysium according to federal book idk about other books please clear this point

[@Hehehehehe653]

Sir book Mai likhai hai Kai I band isotrophic aur wo non.polarzing AP polarizing Bata koi farq hai Kya ya book Mai galat likha hai
