hello everyone and welcome to another anatomy video this is dr ayan from the veterinary anatomy channel in this video we will start talking about the muscles of the hind limb and we will start with the muscles of the hip joint so let's get started so in this video we will dissect some of the muscles of the hip joint starting with the arm muscles including the superficial gluteal muscle the middle gluteal muscle the deep gluteal muscle the beriformus muscle and the tensor muscle of the fasciae later we have a lateral view of the hind limb of the dog so we will start talking about the rum muscles the ram muscles are the muscles which extends between the idiom and the female bone or the thigh so here we are talking about four different muscles the first one which we can see in this area here is the facia the tensor muscle of the facial latae the tensor muscle of the facial letter is triangular shape muscle as you can see here if you dissect this muscle carefully you can divide it into two parts so this is one this is the second part as you can see this muscle originates from the tuber coxa so from the this part of the idiom or from the coxal tuberosity and in cells if you follow the muscle exactly it inserts to the facial later so the facial letter this you know a facial which we can see in this area if you dissect the fish here lata so you can see that the fishy letter has also two layers so the superficial layer this layer here and this is the other layer the deep layer of the facial letter and as you can see part of this muscle inserts with the superficial layer while the other part of the tensor muscle of the facial letter and cells to the deep layer of the facial later again the tensor muscle of the facial letter originates from the coxal tuberosity so let me show you exactly the cocci tuberosity if you look at this picture here so this is a lateral view of the pelvis of the dog here we have the ilium pone with the area with the wing of the idiom here in this area we have this tubercle here called the coxal tuberosity and this is the origin in this case of the tensor muscle of the facial lattice the insertion as we said before to the facial data as you can see here this muscle is innovated by the cranial gluteal nerves and the function of this muscle is to flex as you can see here so contraction of this muscle will flex the hip joint contraction of the tensile muscle of the facial letter will of course flex the hip joint as you can see here the next muscle which we can see here and belongs to the round muscles are the gluteal muscles in general in general we have in the dog here three different uh gluteal muscles the superficial gluteal muscle the middle gluteal muscle and the deep gluteal muscle so we will start with the first one which is located superficially superficially i will move the dog this direction here so this one here the superficial gluteal muscle it's a thin muscle located just under the skin here in this area on the middle gluteal muscle this superficial gluteal muscle originates from the sacrum and also from the gluteal facia which you can see here the gluteal facial found in this area this is the origin of this muscle the insertion of the superficial gluteal muscle is the greater the canter and exactly the lateral service of the greater canter so the superficial gluteal muscle superficial gluteal muscle this muscle is innervated by the caudal gluteal nerve and contraction of this muscle will extend actually the hip joint at the same time because of the origin and insertion of this muscle another function of this muscle is to elevate elevate the hind limb and of course the main function is extension of the hip joint so this was the superficial gluteal muscle superficial gluteal muscle this muscle here just under the superficial gluteal muscle so the superficial gluteal muscle covers actually the caudal part of the other muscle which we can see under here this big muscle called the middle gluteal muscle the middle gluteal muscle is a huge muscle originates from the wing of the ilium from the wing of the ilium and from the iliac crest let me show you the bone again so if you look at the bone here again we say that this is the ilium this is the ilion and this is the wing of the ilio if you remember in one of the videos which we talked about you know previously we said that the lateral surface of the wing of the idiom has what's called the gluteal fossa the gluteal fossa in this case is the origin of the middle gluteal muscle at the same time the middle gluteal muscle originates from the iliac crest this is the iliac crest here the insertion of this muscle is again if you follow the muscle you will find that this muscle inserts to the greater to go cancer to the greater to cancer of the female bone so let me also show you the female bone here so this is the normal location of the femoral bone inside the body and this muscle in this case of course here we have the head of the female bone the neck and laterally we have the greater to cancer so the insertion of this muscle is exactly on this point of the greater cancer of the female pawn so should we one more time show you exactly the original insertion of the middle gluteal muscle it originated from the lia cryst from the gluteal fossa and that means from the wing of the ilium and inserts on the greater trochanter of the female bone this is the middle gluteal muscle the middle gluteal muscle is innervated by the cranial gluteal nerve the the cranial gluteal nerve contraction of this muscle will also extend the hip joint extend the hip joint so contraction of this muscle will extend the hip joint okay now give me please just you know two minutes to cut dissect and cut the middle gluteal muscle and move it to the side so that we can see the deep gluteal muscle under it so seriously [Music] so we came back here as i said before i tried to dissect the superficial gluteal muscle and move it to the side as you can see here um i told you that the superficial gluteal muscle inserts a little bit so naturally on the gluteal canter so if you follow the tendon of it while the middle the gluteal muscle inserts directly to the greater to canter here so what we've done actually we cut you know or we dissected the middle uh gluteal muscle and now we can move it to the side as you can see here just under the middle gluteal muscle we can see this muscle here this muscle is the gluteal muscle the deep gluteal muscle if you look exactly uh originates from the iliac shaft so from the body of the ilium and inserts to the greater uh true counter of the femoral bone so let me also show you the origin of this muscle that originates from this area of the ilium so the shaft of the ilion and inserts of course as we said before to the greater uh true counter of the female bone yeah look exactly and convert between this one and that one here good so the innervation of this muscle of course by the cranial gluteal and the function of this muscle is also to extend the hip joint and at the same time to elevate the hind limb elevate the hind limb and extend the hip joint so the deep gluteal muscle let me put the middle gluteal muscle one more time it's position here it covers completely the deep gluteal muscle so if you want to see the dip you have to dissect the middle and of course the superficial will cover both of them somehow cowardly here so here to be able to see the next muscle which is the veriformus muscle in this case we have to cut the middle gluteal muscle as you can see here we've done this and dissected the middle gluteal muscle up and down just under the middle gluteal muscle in this case here we can see this muscle here the peripheral muscle the bare muscle originates from the last circular vertebrae and the circular tuber ligament and inserts as you can see here to the uh greater trochanter of the femur bone let me show you exactly the borders of this muscle if you put something here you can see how the muscle exactly comes from there and serves to the great autocanta again this muscle is also there for the extension and elevation of the hind limb this muscle the very farmer's muscle is also innervated by a branch comes from the cranial gluteal nerve the bariformis muscle i will move that behind a little bit like this to show you exactly how the muscle looks like the piriformis muscle [Music] you
