Janis tore a ligament in her ankle. Until the injury heals, she is at most risk for which of the following? dislocating bones lo
bulgar [2K]

Answer:

The correct answer is ''dislocating bones.''

Explanation:

When the bone " pops out" or dislodges from its place (joint), a dislocation occurs. An ankle dislocation, like any other joint, occurs when the 2 articular surfaces of the ankle separate, in this case when the talus ( together with the rest of the foot) " pops out of place" and is no longer in contact with the surface of the tibia-fibula. This leads to the complete breakdown of the ligaments that hold the joint in place, causing the bones to " pops out." Producing significant deformities in the affected joint.

How does the endocrine system control body processes? WORTH 20 POINTS
Sidana [21]

Answer:

The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function.

Explanation:

The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.

Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.

Some examples of bodily functions that are controlled by the endocrine system include:

metabolism

growth and development

sexual function and reproduction

heart rate

blood pressure

appetite

sleeping and waking cycles

body temperature

Endocrine system organs

The endocrine system is made up of a complex network of glands, which are organs that secrete substances.

The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.

The glands of the endocrine system include:
