Lab 5: Lymphatic and Respiratory Systems
A. Lymphatic System 
1. Slide 10A (lymph node; section of lymph node; close-up of cortex and medulla)
Find cortex --- medulla --- hilus with blood vessels --- capsule --- germinal centers of secondary nodules --- medullary cords --- sinuses including --- trabecular,  subcapsular (cortical), and medullary sinuses --- trabeculae --- reticular fibers.
 
B. Respiratory System
 A. Histology 
1. Slide #10B (lung)
Find Bronchus (cartilage, PCCE and smooth muscle) --- bronchiole (PCCE with some goblet cells, smooth muscle with adventitia, and little to no cartilage) --- terminal bronchiole (lined with PCCE and wavy mucosa, lamina propria, smooth muscle , adventitia and no goblets) --- respiratory bronchiole (columnar to simple cuboidal epithelium with little underlying smooth muscle and c.t. Alveoli can arise off these.) --- alveolar duct --- alveoli --- alveolar sac with simple squamous epithelium --- visceral pleura.
 B. Models
1. Half head model 
Videos: Nasal Cavity; Pharynx; Larynx 

 Find superior, middle and inferior nasal conchae and their meati --- nasal cavity --- external naris --- vestibule --- olfactory area --- internal naris --- pharyngeal tonsil (adenoid) --- sphenoid and frontal paranasal sinuses --- oropharynx --- laryngopharynx --- lingual tonsil --- palatine tonsil --- fauces --- buccal or oral cavity --- hard palate --- soft palate --- uvula --- tongue --- hyoid bone --- epiglottis --- thyroid cartilage --- cricoid cartilage --- true vocal cords (vocal folds) --- larynx --- false vocal cords (ventricular fold) --- trachea --- esophagus --- nasal septum --- auditory (Eustachian) tube opening.
2. Lung and heart model
Video: Lungs 
 
Find hyoid bone --- thyroid cartilage --- cricoid cartilage --- thyroid ligament --- epiglottis --- true vocal cord (vocal fold) --- false vocal cord (ventricular fold) --- apex of left lung --- apex of right lung --- trachea --- C-rings --- larynx --- thyroid gland --- trachealis muscle --- carina --- primary bronchus (left and right) --- secondary bronchus ---tertiary bronchus --- lobes of each lung --- visceral pleura --- esophagus --- diaphragm --- hilus --- cardiac notch.
 3. Larynx model (anterior view, posterior view, superior view
Videos: Anterior View; Posterior View 

Find hyoid bone --- epiglottis --- thyroid cartilage --- C-rings of trachea --- cricoid cartilage --- arytenoid cartilages --- corniculate cartilages --- true vocal cords --- trachealis.
4. Bronchial tree model  (Sagittal section of model) 
Videos: (Larynx:
Anterior View; Posterior View; Sagittal View); Trachea; Bronchi 
In addition to what is found on the larynx model find left and right primary bronchi --- five secondary (lobar) bronchi --- tertiary (segmental) bronchi --- carina --- thyroid ligament.
