Lab 5: Histology

A comprehensive set of vocabulary flashcards covering the descriptions, subtypes, and anatomical examples of epithelial, connective, muscle, and nervous tissues based on the lecture notes.

Epithelial Tissue

Tissue that covers and lines body structures.

Squamous Epithelial Cells

Flattened cells where a few cells cover large areas.

Simple Squamous Epithelium

Tissue found in blood vessel linings (endothelia), capillaries, serous membranes of the digestive tract, lung alveoli, and parts of the nephron loop.

Stratified Squamous Epithelium

Tissue found in mucous membranes of the mouth, throat, rectum, vagina, and the skin surface.

Cuboidal Epithelial Cells

Intermediate cell shape that is roughly cubic.

Simple Cuboidal Epithelium

Tissue found in the thyroid gland and parts of kidney tubules.

Stratified Cuboidal Epithelium

Tissue found in the ducts of sweat glands.

Columnar Epithelial Cells

Tall, narrow cells that allow many cells to occupy a small surface area.

Simple Columnar Epithelium

Tissue found in the intestinal lining, stomach lining, and kidney collecting ducts.

Stratified Columnar Epithelium

Tissue found in the ducts of salivary glands, the urethra, and mammary glands.

Pseudostratified Columnar Epithelium

Tissue found in the lining of nasal sinuses and the bronchial lining.

Connective Tissue

Tissue that provides support and connects body structures.

Loose Fibrous Connective Tissue

Tissue characterized by much matrix, few cells, and fibers.

Areolar Connective Tissue

A type of loose fibrous tissue found in subcutaneous skin layers (hypodermis).

Adipose Connective Tissue

A type of loose fibrous tissue found in subcutaneous skin layers (hypodermis).

Reticular Connective Tissue

A type of loose fibrous tissue found in the liver, spleen, lymph nodes, and bone marrow.

Dense Fibers Connective Tissue

Tissue where fibers are closely packed with little matrix.

Dense Regular Connective Tissue

Tissue found in tendons, ligaments, and aponeuroses (tendon sheets).

Dense Irregular Connective Tissue

Tissue found in the periosteum, perichondrium (coverings of bones and cartilage), nerve sheaths, and portions of the dermis.

Elastic Connective Tissue

Tissue found in blood vessel walls and elastic ligaments of the spinal column.

Fluid Connective Tissue

Tissue featuring a fluid matrix, many cells, and few or no fibers present.

Blood

A fluid connective tissue consisting of plasma, leukocytes, erythrocytes, platelets, and proteins.

Lymph

A fluid connective tissue consisting of interstitial fluid, leukocytes, and chylomicrons (lipids from intestinal absorption).

Bone Tissue

Tissue containing osteocytes with a matrix mostly comprised of mineral salts.

Compact Bone

Bone tissue found in the shafts of long bones.

Spongy Bone

Bone tissue found in the ends of long bones.

Cartilage

Tissue containing chondrocytes with a matrix composed of a gel of derivative carbohydrates.

Elastic Cartilage

Cartilage found in the ear pinna (flap) and the epiglottis.

Hyaline Cartilage

Cartilage found in laryngeal supports, bronchial rings, and sternum joints.

Fibrocartilage

Cartilage found in intervertebral disks and pads in some synovial joints.

Muscle Tissue

Elongated cells able to undergo contraction.

Skeletal Muscle

Muscle tissue found in appendicular muscles.

Smooth Muscle

Muscle tissue found in blood vessel walls and digestive tract walls.

Cardiac Muscle

Muscle tissue found in the heart.

Nervous Tissue

Consists of neurons and support cells of the nervous system.

Neurons

Electrically stimulated cells that carry signals.

Motor Neurons

Neurons that carry signals to muscles.

Sensory Neurons

Neurons that carry signals from sensory organs.

Interneuron

Central nervous system components that carry signals.

Glial Cells

Support cells of the nervous system, including neurolemmocytes and astrocytes.
