It is a type of epithelia that carry out active transport. eg. Ovarian surfaces, rete testis, kidney tubules, small ducts of exocrine glands
Simple cuboidal
What type of epithelia does the Trachea have?
Pseudo stratified columnar epithelia
What is the difference of an endocrine and exocrine gland?
Endocrine- has no ducts (pituitary, adrenal, thyroid gland, pancreas (islet of langherans)
Exocrine- has ducts (salivary, sweat, oil glands, pancreas (acinar tissues)
What gland that is both an endocrine and exocrine gland?
Pancreas
Endocrine gland- Islet of Lanherans
Exocrine- Acinar tissue

Extra cellular matrix
Embryonic tissue where all connective tissue originates
Mesenchyme
A connective tissue that’s less commonly encountered found in embryonic specimens and in umbilical cord as “wharton’s jelly”

Differentiate Signs from Symptoms
Signs
- Objective evidence
- measurable
- Physical observation
Symptoms
-subjective evidence
-Perceived by patients
A retrogressive change where there is a failure of an organ to form an OPENING
atresia
A developmental change where there is a complete NON-APPEARANCE of an organ
Agenesia
A false hypertrophy can be caused by?
Edema fluid and connective tissue proliferation
Identify the degenerative changes of each situation:
a. Ill-fitting dentures
b. Hypertension
c. Chronic smoker
a. Hyperplasia
b. Hypertrophy
c. Metaplasia
It is a degenerative change where there is regressive alteration in size, shape, orientation that can become cancer
Dysplasia
Marked regressive change in adults cells towards a more primitive or embryonic cell type
Anaplasia
Type of exudate/inflammationwhere mucus is the main component
Catarrhal inflammation
