This could be a number of things, the calf could have a pinched nerve, could have broken hips (result of mother accidentally stepping on it), the best way to discover what the problem is, call your veterinarian, they will be able to view the calf and diagnose the problem.
I hope that this is a help.
First, you have to get her in a head-gate, if she's a bit nervous of you poking around her rear. Then reach inside the birth canal to see if the calf's coming normally. If it's not, you will have to correct the calf yourself or phone the vet to come out and help you. Get the calving chains or calf puller on the calf and start pulling. Pull out and down, and pull when the cow strains. Once the calf is out, get it breathing by clearing the air-way and tickling its nose or ear with a clean piece of straw. Once and if the calf starts breathing and shaking its head, move it to a small pen where you can let the cow in with her new calf. Keep them there for a couple hours or until the calf has been up and suckling at his mother's udder. If you cannot pull the calf out without causing injury to the cow or calf, get the vet out to do a C-section on the cow.
It really depends on the animal. Some animals' feet are simply called feet. However, some of them have specific names. For some, like the dog, the feet are called paws. For some, like the cow, the feet are called hooves.
This is likely a pig being restrained for field castration, but this method is not often used for humane reasons.
Legs :)
Get her in a head gate, preferably one in a calving pen, if you have one, or a headgate with the squeeze chute side settings set as wide as possible. Next you'll have to glove up (use shoulder-length gloves if you a bit squeemish of going in bare-handed) and go inside the cow's vagina into her uterus to see if the calf is not presented normally. A dystocia calf may have one or two legs turned back, his head turned back, he may be backwards (a breach), or there may be twins that are causing trouble. If it's a simple problem like head turned back or a foot turned back, it shouldn't be too hard to get him in proper position. But you have to be careful about how you get him in position so you don't tear the uterine wall by accident. With feet or head, you have to push the calf back away from the birth canal (against the cow's contractions). With the head malpresentation, reach in and cup your hand around the calf's nose and turn his head so that it's facing towards you (or the rear of the cow). With the leg, cup your hand around the calf's hoof and pull the leg up until it is parallel with the calf's neck. With more difficult presentations like a breach or twins, you may have to call a vet. Other dystocia factors that make it difficult for a cow (or a first-calf heifer) to calve out is that the calf may be too big. A vet is mandatory in this case, as a C-section will have to be done. Make sure you catch the problem early and don't wait for 24 hours after you see the signs of a cow having problem calving out. If you see a cow that is having problems calving, first wait for 2 to 4 hours, and if nothing has progressed, then phone the vet. If you wait for 24 hours or more, you will have a dead calf (and possibly a cow, if you've left it for 3 or 4 days) on your hands.
Between your legs at the rear.
When a dog runs away from something in fear (usually after a fight), it will tuck its tail between its rear legs so its tail can't get bitten off. This is the origin of the phrase, so if someone runs away "with their tail between their legs", then they just lost an argument and are backing away.
Seals do not have legs they have 2 front flippers and a rear tail.
Strong rear legs.
There are a great variety of Dragons. Some have six legs but in the majority the second pair has evolved into a pair of wings. Some Dragons have lost the last pair of legs and have only wings and front legs. The Chinese Dragon has only four legs having lost the mid-pair altogether. Some have lost all their legs: Knuckers and Hydra. Then there are rare weird things that are deemed to belong to the same class as Dragons that have odder physiques. One such is the Vlariak River Dolphin. This blind bottom dweller has one rear leg with a webbed fin-like foot that it uses as a rudder. And some Dragons have four legs and a pair of wings. [European Dragon, etc.]
there antlers and their rear legs
The group of muscles at the rear top of your legs is called the hamstrings. These muscles are responsible for bending the knee and extending the hip.
18. Five on each front foot, and four on each rear foot, the same as other cats.The same as any other cat, five on both front paws and four on the rear paws.
it has enlarged rear legs for jumping and the back legs are facing backwards to spring into action and run (jump) away!!!
Generally on four legs. Upright posture is not for moving.
Veal Heel meat is from the rear leg and thigh area of the cow. Veal is from a young calf.
The monkey muscle is in the bottom half of the leg at tha rear around the calf muscle.
