In acromegaly, excess growth hormone leads to increased levels of insulin-like growth factor 1 (IGF-1), which stimulates the growth of various tissues, including bone. Membranous bones, such as the skull, jaw, and hands, are particularly affected because they undergo intramembranous ossification, where bone forms directly from mesenchymal tissue. The continuous stimulation of these growth pathways results in abnormal enlargement and thickening of these bones, contributing to the characteristic features of acromegaly.
Acromegalic means "pertaining to or characteristic of acromegaly", or a person affected by acromegaly, a disease involving enlargement of the bones of the hands, feet, face and jaw.
a tortuous anatomical structure; especially : the inner ear or its bony or membranous part -- see BONY LABYRINTH, MEMBRANOUS LABYRINTH ; the cavity in the petrous portion of the temporal bone that contains the membranous labyrinth of the inner ear -- called also osseous labyrinth
Membranous bone. To remember which bones are membranous vs. cartilaginous, think of it this way: cartilage has no time to grow in the place of what will become membranous bones, though it does for cartilaginous. This means that membranous bone develops before cartilaginous bone. I don't know how true this is ontogenetically, but it works for me.As membranous bone is the type of bone which develops first, it follows that it would be the type which provides the most important protection: cranial, vertebral, facial (excluding the mandible, I believe), and if I remember correctly, the ribs, sternum, and clavian bones are all membranous bones. Limb bones are all cartilaginous.n.A bone that forms directly in membranous connective tissue, as some cranial bones, instead of developing from cartilage.Read more: membrane-bone

Acromegaly causes a number of physical changes over time. Since growth hormone is responsible for organ, bone, and muscle development, overproduction leads to an abnormal growth of these tissues. People with acromegaly may have swelling in the hands and feet and develop a harsh facial appearance as the jawbone protrudes, the tongue enlarges, and the chest rounds. The heart grows, which impairs its function, and other tissue growth constricts the nerves, causing weakness, vision impairment, and headaches. In many cases, bone deformation causes joint pain, which can lead to severe arthritis.Skeletal SystemNervous SystemrespiratoryPretty much all systems are affected
Acromegaly is a disease, so you could write something like this: "Acromegaly is a hereditary disease which concerns the extremities of the body".
The cannon bone of a horse's leg is affected when they get bucked shins.
Acromegaly is caused by prolonged overproduction of GH by the pituitary gland.
acromegaly
No, acromegaly is not contagious. It is a rare hormonal disorder caused by the overproduction of growth hormone in the pituitary gland. Acromegaly typically results from a noncancerous tumor in the pituitary gland.
Bone
The medical term for the structure surrounding the bone is "periosteum." The periosteum is a fibrous membrane that covers the outer surface of bones and plays a role in bone growth, repair, and nourishment.
