Answer: An intentional cut through intact tissue for the purpose of exposing or excising underlying structures is called an "Incision." The correct option is a.
Step-by-step explanation:
An incision is a deliberate and controlled cut made in tissue or skin using a surgical instrument, such as a scalpel. It is performed with the specific intention of accessing or removing underlying structures, such as organs, blood vessels, or abnormal tissue.
Here's a breakdown of why option a is the correct answer:
1) Incision: An incision is a planned and precise cut made by a healthcare professional during a surgical procedure. It involves using a sharp instrument, such as a scalpel, to create a clean opening in the tissue. This technique allows for better visibility and access to the desired area.
2) Laceration: A laceration, on the other hand, refers to an unintentional or accidental tear or irregular wound caused by a blunt force or trauma. Unlike an incision, a laceration is not intentionally made for surgical purposes.
3) Abrasion: An abrasion is a superficial wound that occurs when the outer layers of the skin are scraped or rubbed off. It does not involve cutting through intact tissue.
4) Avulsion: Avulsion refers to the tearing away of tissue or a body part from its normal position, usually due to forceful trauma. It is different from an intentional incision made by a healthcare professional.
In summary, an intentional cut through intact tissue for the purpose of exposing or excising underlying structures is called an "Incision." It is a controlled surgical procedure performed by healthcare professionals to access specific areas or remove tissues or organs.
