A layer of glycoproteins and a network of fine protein filaments that prevents the movement of proteins and other large molecules from the connective tissue to the epithelium describe
(a) Interfacial canals
(b) The basement membrane
(c) The reticular lamina
(d) Areolar tissue
(e) Squamous epithelium
검증된 단계별 안내1
Step 1: Understand the key components described in the problem. The question mentions a layer of glycoproteins and a network of fine protein filaments that act as a barrier preventing the movement of proteins and large molecules from connective tissue to the epithelium.
Step 2: Recall the structure of the basement membrane, which is a specialized extracellular matrix located between the epithelium and connective tissue. It consists of two main layers: the basal lamina (rich in glycoproteins) and the reticular lamina (composed of protein filaments).
Step 3: Identify the function of the basement membrane, which includes acting as a selective barrier that restricts the passage of large molecules and proteins, supporting epithelial cells, and anchoring them to the underlying connective tissue.
Step 4: Compare the options given: (a) Interfacial canals are not related to this barrier function; (c) The reticular lamina is part of the basement membrane but alone does not describe the entire barrier; (d) Areolar tissue is a type of connective tissue, not a barrier layer; (e) Squamous epithelium is a type of epithelial tissue, not a barrier layer between tissues.
Step 5: Conclude that the correct description corresponds to (b) The basement membrane, as it matches both the structural components (glycoproteins and protein filaments) and the functional role of preventing movement of proteins and large molecules from connective tissue to epithelium.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.
Basement Membrane
The basement membrane is a thin, dense layer of glycoproteins and protein filaments located between the epithelium and connective tissue. It acts as a selective barrier, preventing large molecules and proteins from passing freely, thus maintaining tissue integrity and supporting cell attachment.

Glycoproteins and Protein Filaments
Glycoproteins are proteins with carbohydrate groups that contribute to the structural framework of the basement membrane. Protein filaments, such as collagen, form a network that provides mechanical strength and filtration properties, controlling molecular movement between tissues.

Connective Tissue and Epithelium Interface
This interface is where the basement membrane resides, separating connective tissue from epithelial layers. It regulates exchange of substances, supports epithelial cells, and plays a role in tissue repair and regeneration by anchoring cells and filtering molecules.

Why does damaged cartilage heal slowly?
(a) Chondrocytes cannot be replaced if killed, and other cell types must take their place.
(b) Cartilage is avascular, so nutrients and other molecules must diffuse to the site of injury.
(c) Damaged cartilage becomes calcified, thus blocking the movement of materials required for healing.
(d) Chondrocytes divide more slowly than other cell types, delaying the healing process.
(e) Damaged collagen cannot be quickly replaced, thereby slowing the healing process.

During a lab practical, a student examines a tissue that is composed of densely packed protein fibers that run parallel to each other and form a cord. There are no striations, but small nuclei are visible. The student identifies the tissue as skeletal muscle. Why is the student's choice wrong, and what tissue is he probably observing?
