Skeletal System

Digenetic trematodes typically have an excretory system composed of flame cells (protonephridia) and collecting tubules. Flame cells are specialized cells that remove waste and regulate osmotic balance by using cilia to move fluids through tubules. Waste products are expelled through excretory pores. These structures help regulate the internal environment of the parasite and maintain homeostasis.

It could be many different things, for example a possible fracture if you have fallen. The bone starts to heal and in doing so a hard nodular lump can form which will eventually disappear. If it is a break, and the bone is misaligned, then the new bone will reform, leaving a lump of new bone, which will not go away, but wont be painfull. But without seeing it, it is very hard to guess. Go see your local doctor. It could be an insect bite that has become infected, or a million other things. Go see you local GP, and get confirmation.

The density of water is 1.0 and people are made mostly of water but they do float in water (just) so the density of a person is lust less than 1.0.

I can not give you a precise answer because of cause your density would change as you breath in and out.

Those are the bursa (the sacs of liquid between your vertabrae) suddenly expanding. It's harmless, really. It also means you have nice loose neck muscles. If your neck continually pops around the top of your head, I would not commend you on nice, loose neck muscles. A "pop" sound is not comming from a bursa between your vertabrae. Vertabrae, in fact, do not house bursae in any intervertebral manor. A vertebral disc is what sits in between two vertebrae (this creates a joint.) A bursa is a liquid sac that helps ligamentous and tendonous structures slide more easily past each other. These are found in larger joints, such as the knee, hip and shoulder. An articulation or a joint "pops". This sound comes from a release of nitrogen gas from the tissues that surround a joint, when there is a sudden negative pressure within the joint. This is harmless if it happens once in a blue moon, but if you experience this with any frequency, it is a sign of hypermobility or too much joint motion. This can lead to a problematic instability and even spinal degeneration. A chiropractor is the expert to see in this situation.

Race does not affect the amount of bones a person has. All people, regardless of race, have the same number of bones.

It actually works more with children because we are much cuiter then adults!

A buried bone may appear as a protruding object in the ground, possibly with dirt or soil covering part of it. It may also be visible as a small bump or mound on the surface where the bone is buried. Over time, natural processes like erosion or animal activity could expose parts of the bone.

yes.

A school, company, or shoal., The skeleton of the head of a vertebrate animal, including the brain case, or cranium, and the bones and cartilages of the face and mouth. See Illusts. of Carnivora, of Facial angles under Facial, and of Skeleton, in Appendix., The head or brain; the seat of intelligence; mind., A covering for the head; a skullcap., A sort of oar. See Scull.

It depends on the size of it. It can really be any amount. We have a couple that are about the size of an apple (but flatter), and those were about 10 bucks probably. But they can probably get really expensive too!

The innominate bone or coxal bone

The four bones that form the ankle joint are the tibia, fibula, talus, and calcaneus. The tibia and fibula are the bones of the lower leg that articulate with the talus, which sits on top of the calcaneus, or heel bone.

The tarsals, as well as the lower regions of the tibias and fibulas.

The scientific name for finger bone is phalanx bones.

The bones specifically involved in the ankle joint are the tibia, fibula and talus.

Any of the joints that unite the tarsal bones. (Tarsals)

The scientific name for the collar bone is clavicle. It is a long bone that connects the arm to the body and helps with shoulder movements.

Os temporale is the scientific name for 'temporal bone'. The temple bone actually is made up of four parts: the tympanic, the squama temporalis, the petrous or pyramid, and the mastoid. The noun 'os' means 'bone'. The adjective 'temporale' means 'of or relating to the temple'. The phrase is pronounced 'ohs tehm-poh-RAH-lay'.

The growth plate is the part of your foot right before your toes. (i would know I broke it :()

There are also growth plates in your ankle, leg, elbow, and all your other bones. Just so you know. I broke the one in my ankle :(

Compact bone makes the bones hard enough so that they can provide support to the body and protect organs. It makes up the hard exterior of skeletal bones.

Spongy bone (cancellous bone) is in shorter, flatter bones, and at the ends of long bones. It has more blood vessels and usually contains bone marrow, where red blood cells are produced.

In old age the jelly filling the intervertebral discs cushioning the spinal column begins to dry out. And this desiccation causes their side walls to begin to bulge like the sidewalls of a car tire as it gets low in air.

The answer to this very complicated question is both yes and no. My father was only 56 years old and had won the battle over stage 4 colon cancer when he went to the doctors office for a simple procedure he had had done several times before. This time was different - he went into cardiac arrest and his heart wasn't able to be started for over 20 min. He was pronounced brain dead. His body otherwise was healthy including his heart. He was brain dead because his heart had quit beating for 20 minutes and therefore his brain went without oxygen for 20 minutes thus causing him to become brain dead. He was on a ventilator for 48 hours and the doctor said even if he were to wake up right then he would not know anything or anyone. So basically be a vegetable. I know my father would not want to live this way. The doctors gave us a choice and we chose to take him off the ventilator and he passed away peacefully in about 5 minutes. Until then, his body was alive but his brain was dead.

Spondylolisthesis is the forward displacement of one vertebra over the one beneath it. It commonly occurs in the lower lumbar region, especially between the fifth lumbar vertebra and the first sacral vertebra (L5-S1).

The lumbar vertebrae are located in the lower back region of the human spine, between the thoracic vertebrae and the sacrum. There are five lumbar vertebrae (L1 to L5) that support the weight of the upper body and allow for bending and twisting movements of the trunk.
