Step-by-step solution for: Unit 1 Tissue Types Review Worksheet | Study notes Cellular and ...
Here is the correct matching of each structure with its appropriate tissue type, along with a brief explanation for each:
---
1. Lining the small intestine → F. Simple Columnar Epi.
*Explanation:* The small intestine is lined with simple columnar epithelium to facilitate absorption and secretion. Its cells are tall and closely packed, ideal for nutrient uptake.
2. Outer layer of bone → R. Compact Bone
*Explanation:* Compact bone forms the dense, hard outer layer of bones, providing strength and protection.
3. Hypodermis → J. Adipose
*Explanation:* The hypodermis (subcutaneous layer) is primarily composed of adipose tissue, which stores energy and insulates the body.
4. Visceral peritoneum → A. Simple Squamous Epi.
*Explanation:* Serous membranes like the visceral peritoneum are lined with simple squamous epithelium to reduce friction between organs.
5. Liver → D. Simple Cuboidal Epi.
*Explanation:* Liver hepatocytes are often described as cuboidal in shape and function in secretion and absorption — though technically liver tissue is glandular parenchyma, it’s commonly matched with simple cuboidal in basic histology worksheets.
*(Note: Some sources may argue liver is not epithelial, but in this context, “Simple Cuboidal Epi.” is the best fit among options.)*
6. Within the epiphyses (ends of long bones) → S. Spongy Bone
*Explanation:* The epiphyses contain spongy (cancellous) bone, which houses red bone marrow and provides shock absorption.
7. Reticular layer of dermis → L. Reticular CT
*Explanation:* The reticular layer of the dermis consists of dense irregular connective tissue with collagen and elastic fibers — specifically called reticular connective tissue in some classifications.
8. Epiglottis → Q. Elastic Cartilage
*Explanation:* The epiglottis needs flexibility to cover the trachea during swallowing — elastic cartilage provides this property.
9. Spleen → K. Areolar CT
*Explanation:* The spleen contains loose connective tissue (areolar CT) that supports its lymphoid structures and blood vessels. *(Note: While spleen is mostly lymphoid tissue, "Areolar CT" is the closest match among given choices for its supportive stroma.)*
10. Epidermis → C. Keratinized Stratified Squamous Epi.
*Explanation:* The epidermis is the outermost skin layer and is composed of keratinized stratified squamous epithelium for protection against abrasion and water loss.
11. Costal cartilage → O. Hyaline Cartilage
*Explanation:* Costal cartilages connecting ribs to sternum are made of hyaline cartilage — smooth, flexible, and supportive.
12. Esophagus → G. Stratified Columnar Epi.
*Correction:* Actually, the esophagus is lined by Non-Keratinized Stratified Squamous Epi. (B) — NOT stratified columnar. Stratified columnar is rare and found in parts of the male urethra and large ducts.
✔ Correct Match: 12 → B. Non-Keratinized Strat. Squamous Epi.
13. Tendons and ligaments → N. Dense Regular CT
*Explanation:* These structures require high tensile strength in one direction — provided by dense regular connective tissue with parallel collagen fibers.
14. Lining the trachea → H. Pseudostratified Ciliated Columnar Epi.
*Explanation:* The trachea is lined with pseudostratified ciliated columnar epithelium with goblet cells to trap and move mucus and debris upward.
15. Lining the oral cavity → B. Non-Keratinized Strat. Squamous Epi.
*Explanation:* The oral cavity lining is moist and non-keratinized stratified squamous epithelium to withstand abrasion while remaining flexible.
16. Papillary layer of dermis → K. Areolar CT
*Explanation:* The papillary layer is composed of loose connective tissue (areolar CT) that supports capillaries and nerve endings near the epidermis.
17. Periosteum → M. Dense Irregular CT
*Explanation:* The periosteum is a fibrous membrane covering bones, composed of dense irregular connective tissue for attachment and protection.
18. Intervertebral discs → P. Fibrous Cartilage
*Explanation:* Intervertebral discs are made of fibrocartilage, which combines strength of collagen fibers with elasticity to absorb shock.
19. Lining the urinary bladder → I. Transitional Epi.
*Explanation:* Transitional epithelium allows stretching and recoil — essential for the urinary bladder as it fills and empties.
20. Pubic Symphysis → P. Fibrous Cartilage
*Explanation:* The pubic symphysis is a cartilaginous joint stabilized by fibrocartilage, allowing limited movement and shock absorption.
