Wearing inappropriately tight shoes can put undue pressure on feet. such pressure may then lead to painful heterotopic bone formation in the soft tissues of the foot. what medical term describes this condition?

Sesamoid is the medical term that describes this condition

Sesamoid is a small nodular bone that is firmly fixed in a tendon or muscle. Sesamoid forms as a result of pressure, or it can form normally on its own. Sesamoids are present in many joints in the body such as in the foot and knee. Sesamoids functions like pulleys for tendons. They enhance the ability of the tendons to transmit muscle forces by creating a smooth surface for the tendons to slide over.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
