Revision Quiz- Organization Of The Body

The correct answer is Nervous. Nervous tissue is responsible for communication in the body. It consists of specialized cells called neurons that transmit electrical signals throughout the body, allowing for communication between different parts of the body and the brain. Nervous tissue plays a crucial role in coordinating and controlling bodily functions, as well as receiving and interpreting sensory information.

The word "cutaneous" refers to anything related to the skin. It is derived from the Latin word "cutis" which means skin. Therefore, "cutaneous" is the correct answer for the word for skin.

The membrane is responsible for controlling what moves in and out of the cell. It acts as a barrier, allowing certain substances to enter or leave the cell while preventing others from doing so. This selective permeability is crucial for maintaining the cell's internal environment and regulating the exchange of nutrients, waste products, and signaling molecules. Without a functioning membrane, the cell would be unable to properly interact with its surroundings and carry out essential processes for survival.

Epithelial tissue is the correct answer because it is responsible for protection and secretion in the body. Epithelial tissue covers the surfaces of organs, lines body cavities, and forms glands. It acts as a barrier to protect underlying tissues from injury, infection, and dehydration. Additionally, epithelial tissue also secretes various substances such as mucus, enzymes, and hormones. Therefore, epithelial tissue is crucial for both protection and secretion functions in the body.

Muscular tissue has the function of contractibility. This tissue is made up of specialized cells called muscle fibers that have the ability to contract and generate force. The contraction of muscular tissue allows for movement of body parts, such as the contraction of skeletal muscles for voluntary movements or the contraction of smooth muscles in organs for involuntary movements like digestion. Muscular tissue is also responsible for generating heat and maintaining body temperature.

The nucleus is the part of a cell that regulates the cell's functions. It contains the cell's DNA and controls the production of proteins and other molecules necessary for the cell's activities. The nucleus acts as the cell's control center, directing the cell's activities and maintaining its overall function and integrity.

A cell stores 23 pairs of chromosomes in the nucleus. Each pair consists of two chromosomes, one from each parent, for a total of 46 chromosomes. These chromosomes contain the genetic information that determines an individual's traits and characteristics.

Blood is a specialized form of connective tissue because it is composed of cells suspended in a fluid matrix called plasma. Connective tissue is characterized by its ability to connect, support, and protect other tissues and organs in the body. Blood performs various functions such as transportation of oxygen, nutrients, and waste products, regulation of body temperature, and immune responses.

Ribosomes are responsible for protein synthesis, both within the cell and for export out of the cell. They are the site where amino acids are assembled into proteins based on the instructions provided by the cell's DNA. Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum. Therefore, ribosomes are the correct answer for this question.

Vacuoles are empty spaces within the cytoplasm that are used for temporary storage or transportation in the cell. They can contain waste materials or secretions from the cytoplasm. The nucleus is the control center of the cell, the endoplasmic reticulum is involved in protein synthesis and transport, and lysosomes are responsible for breaking down waste materials. Therefore, the correct answer is vacuole.

The word "cubital" refers to the elbow. It is derived from the Latin word "cubitus," which means elbow. This term is commonly used in medical and anatomical contexts to describe anything related to or located near the elbow joint. Therefore, "cubital" is the correct answer for the word that means elbow in this question.

The cytoplasm is the correct answer because it is the part of the cell where most cellular metabolism takes place. It is a gel-like substance that fills the cell and contains various organelles, such as mitochondria and ribosomes, which are involved in processes like energy production and protein synthesis. The cytoplasm also serves as a medium for the transportation of molecules and nutrients within the cell.

The word "cephalic" refers to the head or related to the head. It is derived from the Greek word "kephalē," which means head. Therefore, "cephalic" is the correct answer as it directly relates to the word "head."

The endoplasmic reticulum is an organelle that serves as an intracellular transport system. It is a network of membranous tubules and sacs that extends throughout the cytoplasm of eukaryotic cells. The endoplasmic reticulum is involved in the synthesis, folding, and transport of proteins, as well as the synthesis of lipids. It plays a crucial role in the transportation of molecules within the cell, allowing for the efficient movement of proteins and lipids to their appropriate destinations.

A vesicle is a small, intracellular, membrane-enclosed sac that stores or transports substances within a cell. It is a common organelle found in eukaryotic cells and plays a crucial role in various cellular processes such as protein transport, secretion, and storage of molecules. Vesicles can bud off from the Golgi apparatus or other membrane structures and can fuse with other organelles or the cell membrane to release their contents. They are versatile structures that aid in the organization and functioning of cells.
