Biology 2101 Histology Lab Test 1 Flashcards

Comprehensive practice questions covering histology, tissue types, locations, and functions as presented in the Biology 2101 Lab Test 1 lecture notes.

What are the locations and function of Areolar Connective Tissue?

Location: Associated with organs and in the dermis of skin; Function: Elasticity.

What is the primary function and locations of Reticular Connective Tissue?

Function: Filtration; Location: 'Framework' of liver, lymph nodes, and spleen.

Where is Adipose Tissue located and what are its functions?

Location: Hypodermis, around organs, within muscles, and around nerves; Function: Long term energy storage and insulation.

What are the three main components of mammalian blood shown in a blood smear?

Leukocytes, Platelets, and Erythrocytes.

Describe the difference in location and fiber arrangement between DWFCT Regular and DWFCT Irregular.

DWFCT Regular: Mammal Tendon and Ligaments, fibers run parallel; DWFCT Irregular: Dermis, fibers in an irregular pattern.

List the three main layers of the Human Scalp as identified at 4x magnification.

Epidermis, Dermis, and Hypodermis.

What are the structural components of an Osteon in Compact Bone?

Matrix in concentric rings, Canaliculi, Haversian Canal, and Osteocytes.

Where is Hyaline Cartilage located and what is its function?

Location: Trachea, ends of long bones, part of nasal septum, ribs, sternum, larynx, and bronchi; Function: Protection and support.

What specific features distinguish Elastic Cartilage from Hyaline Cartilage?

Elastic Cartilage contains Elastic Fibers in the matrix and provides flexibility.

Where is Fibrocartilage found and what is its visual nickname?

Location: Pubic symphysis and intervertebral discs; Note: 'Blue Cotton Candy!'

What are the specific locations of Simple Squamous and Simple Cuboidal Epithelium in the kidney?

Simple Squamous: Outer lining/edge of the top of the nephron; Simple Cuboidal: Nephron Tubules.

What is the location and function of Simple Columnar Epithelium?

Location: Gall Bladder; Function: To store and concentrate Bile.

How can you distinguish Keratinized from Non-Keratinized Stratified Squamous Epithelium?

Non-Keratinized (Vagina) has nuclei in the top layer cells; Keratinized (Epidermis) has no nuclei in top layer cells and contains keratin.

What is the location and function of Pseudostratified Ciliated Columnar Epithelium (PSCCE)?

Location: Trachea; Function: Mucociliary elevator.

Where is Transitional Epithelium located and what is its function?

Location: Urinary Bladder; Function: Distension.

What are the characteristics and visual description of Smooth Muscle Tissue?

Characteristics: Non-striated, involuntary, moves organs; Description: 'Pink Toothpicks!!'

What are the defining characteristics of Cardiac Muscle fibers?

Striated, involuntary, mono-nucleated, branching or woven appearance, and contains Intercalated Discs.

Contrast Skeletal Muscle with Cardiac Muscle based on fiber structure.

Skeletal Muscle is voluntary, non-branching, and consists of poly-nucleated cells.

Name the parts of a Giant Multipolar Neuron identified in the notes.

Dendrites, Cell Body, Axon, and Neuroglial cells.

What cell type is found in the Human Cerebral Cortex and what is the cortex's function?

Cell: Pyramidal Cell; Function: Cognition.

Contrast the Meissner’s Corpuscle and the Pacinian Corpuscle by location and function.

Meissner’s: Dermal Papillae, light touch receptor; Pacinian: Deep Dermis to Hypodermis, deep pressure receptor.

List the phases of the Cell Cycle and Mitotic Cellular Division.

Interphase, Prophase, Metaphase, Anaphase, and Telophase.
