Practical 2 Histology

Smooth Muscle

Connective Tissue

Ciliated Cell

Goblet Cell

Trachea

Lined by resp epithelium, cartilage, smooth muscle, glands, immune tissue, adventitia

Bronchus

Irregular patches of cartilage, limited smooth muscle, sero/mucous glands, resp epithelium

Bronchiole

No cartilage, smooth muscle present, few to no glands, decreasing numbers of goblet cells, resp epithelium in simple ciliated columnar

Alveolar Duct

Respiratory Bronchiole

Terminal Bronchiole

Alveoli

Alveolus

Endocardium

Inner most layer(simple squamous) and underlying CT. Conducting Cells can be found in CT

Myocardium

Cardiac muscle cell layer. Largest layer. Sparse CT between cells

Epicardium

Outermost layer, simple squamous cell layer and underlying CT

Cardiac Myocyte

Branching networks of fibers, single centrally located nucleus. Striation due to presence of sarcomeres. High vascularity

Purkinje Fibers

large diameter, pale staining cytoplasm

Cardiac Skeleton

4 rings of dense fibrous CT

Intercalated Discs

Tight junctions, desmosomes, and gap junctions
