Cells

Cancer is a disease characterized by the uncontrolled growth and spread of abnormal cells in the body, leading to harmful effects on the individual's health and well-being.

Muscle tissue is primarily responsible for movement in the body by converting chemical energy from our food into mechanical energy through contraction.

Connective tissue mainly serves to support, bind, and protect other tissues in the body. It is known for being one of the most abundant and widely distributed tissues throughout the body.

Malignant melanoma is a serious type of skin cancer that requires timely detection and intervention to prevent further complications.

Malignant neoplasms are characterized by their ability to grow aggressively, invade surrounding tissues, and spread to other areas of the body if left untreated. They can be life-threatening and require aggressive treatment.

Staging is the process of assessing the extent of cancer spread, which helps in determining the appropriate treatment plan and prognosis for the patient.

Erythrocytes, also known as red blood cells, are specialized for the transport of oxygen and carbon dioxide in the bloodstream.

Semi-malignant neoplasms are known to grow locally destructive but do not spread. Although they may cause death if untreated, they can be cured through surgical removal or radiation treatment.

Dysplasia refers to abnormal cellular changes that are localized to the original tissue and have the potential to develop into cancer over time.

The nucleus is the control center of the cell and contains the cellular DNA, responsible for coordinating and regulating all cellular activities.

Leukocytes, or white blood cells, are primarily involved in the immune response by identifying and eliminating foreign invaders and abnormal cells. They do not directly contribute to blood clotting, oxygen transport, nutrient storage, or pH regulation.

Epithelial tissue serves as a protective barrier and lining for internal and external surfaces, as well as glandular functions. It is not responsible for transmitting electrical signals, providing structural support, or facilitating voluntary muscle movement.

Radiation therapy is typically used in conjunction with surgery or in cases where the tumor is too large to be surgically removed. It is not always the first-line treatment for all types of cancer, nor is it solely used for relieving pain in advanced stage cancers.

Stage 0 cancer signifies that cancer cells are localized and have not spread beyond their original site, making it highly treatable with good outcomes through surgical intervention.

Basal cell carcinoma (BCC) is indeed the most common form of skin cancer that is semi-malignant and typically does not metastasize but grows locally invasive. The incorrect answers provided are common misconceptions that do not accurately define BCC.

Nervous tissue is specifically responsible for the functions described in the correct answer.

Skeletal muscles play a crucial role in movement and locomotion by receiving signals from the nervous system to contract, thereby allowing the body to interact with its environment. The other incorrect answers do not accurately describe the function of skeletal muscle.

The correct definition of 'benign' refers to a neoplasm that is non-cancerous and does not cause damage to surrounding tissues or spread to other parts of the body.

Cardiac muscle is unique in its characteristics and functions, as it is specifically adapted to pump blood through the circulation. Unlike skeletal muscles and smooth muscles, cardiac muscle is found exclusively in the heart and is involuntary in nature, meaning it cannot be controlled consciously. Its ability to generate its own contraction rhythm allows the heart to beat continuously without external influence.

A sarcoma specifically refers to a type of cancerous tumor that originates in the cells of connective tissues such as bone, cartilage, fat, muscle, and other soft tissues.

TMN staging is a system used to describe the extent of a cancer's growth within the body, incorporating tumor size, lymph node involvement, and metastasis presence to guide treatment decisions.

The suffix -oma is used to indicate any tumor, whether benign or malignant, regardless of the cause. It is a general term that covers a wide range of tumor types.

Stage IV cancer indicates the most advanced stage where cancer has spread to distant parts of the body, making it difficult to treat and manage.

An in situ lesion refers to cancer that is still contained and growing in its original location, rather than spreading to other parts of the body.

Chemotherapy involves the use of drugs to destroy cancer cells. It is known for its side effects due to its impact on fast-growing cells, such as hair follicles and cells in the digestive system.

A hematoma is a localized accumulation of blood in the tissue, typically due to trauma or injury.

Stage I, II, III in cancer staging typically indicate the extent of cancer spread, with Stage III indicating that cancer is present and may have localized or regional metastasis.

Cells are the basic structural and functional units of life, responsible for carrying out all the processes necessary for an organism to survive and thrive.
