"Hemianopsia" Natural Recordings by Native Speakers
Hemianopsia is a type of visual field defect in which a person's peripheral vision is reduced or absent on one side of their visual field. It can be thought of as "looking through a tunnel" with a blind spot on one side. Hemianopsia can be caused by a variety of factors, including stroke, brain tumor, head injury, or other neurological disorders.
Hemerocallidaceae is a family of plants in the order Asparagales. Members of this family are commonly known as daylilies or spider lilies. They are perennial plants that typically have long, narrow leaves and produce showy, funnel-shaped flowers in a wide range of colors.
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.
Hemianopia is a type of visual field defect that occurs when a person loses the ability to see part or all of one half of their visual field due to damage to the visual processing areas in the brain. It can result from a variety of causes, including stroke, traumatic brain injury, tumors, or inflammatory diseases such as multiple sclerosis. Hemianopia can be partial, causing only a small deficiency in vision, or it can be complete, causing a complete loss of vision in one half of the visual field.
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.
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.
