"Hemiaplasia" Natural Recordings by Native Speakers
Hemiaplasia is a medical term that refers to the condition where there is an absolute absence or underdevelopment of half of a limb or digit. It is a type of congenital anomaly, meaning it is present at birth. In individuals with hemiaplasia, the affected limb is typically smaller than the normal counterpart and may be absence of certain muscles, bones, or other structures. This condition can occur on either the upper or lower extremities, and the severity of the condition can vary widely from individual to individual.
Hemerocallis refers to a genus of flowering plants commonly known as daylilies. They are herbaceous perennials that produce showy, trumpet-shaped flowers that bloom for only one day. The term "hemerocallis" comes from the Greek words "hemera" meaning day and "kalos" meaning beauty, referring to the plant's short-lived but striking blooms.
A hemiacetal is a type of organic compound that is formed when an alcohol reacts with an aldehyde or a ketone in the presence of acid. It is a half-ester of the original aldehyde or ketone and an alcohol. Hemiacetals are important in the formation of many natural products, such as starches, cellulose, and other biopolymers. They can also be used as intermediate compounds in the synthesis of other organic compounds.
Hemianesthesia is a medical term that refers to a type of nerve damage or dysfunction that results in a decrease or loss of sensation on one side of the body. This sensation can be in the form of numbness, tingling, weakness, or loss of proprioception (the sense of body position and movement). In hemianesthesia, the affected side of the body may feel as if it is anesthetized or numb, hence the name. It is often the result of damage to the spinal cord, brain, or peripheral nerves.
Hemiballism is a rare neurological disorder characterized by abnormal involuntary movements, specifically tremors and chorea (involuntary jerky movements), predominantly affecting one side of the body. The term "hemiballism" literally means "half-ballism", with "hemi-" referring to half and "ballism" referring to the sudden, jerky movements of the affected limbs.
