In order for you to understand what I am
talking about, I’ll show and introduce to you the tissues present in a human
body.
By the way, HISTOLOGY is the study of tissues.
And TISSUES are collection of similar cells and the substances surrounding the
cells.
There are four types of tissues:
Epithelial tissue
- protects underlying structures
- acting as barriers
- permitting the passage of substances
- secrete substances
a. Simple squamous
b. Simple cuboidal
c. Simple epithelium
d. Pseudostratified columnar
e. Stratified squamous
f. Stratified cuboidal
g. Stratified columnar
h. Transitional

I am now than with Epithelial Tissue, our next topic will be about GLANDS. Glands is a secretory structure.
- Endocrine glands- do not have ducts
- Exocrine glands- they have ducts
Here is a discussion about endocrine and exocrine glands,a video that will give you the big differences of the two.
Connective tissue is easier to identify rather than epithelium tissue because most of the tissues has different structures.
Connective tissue
- form a layer to separate tissues and organs
- connect tissues to one another.
- they store minerals
- transporting
- protecting
a. Dense Regular Collagenous
b. Dense Regular Elastic
c. Dense Irregular Collagenous
d. Dense Irregular Elastic
e. Adipose Tissue
f. Reticular Tissue
g. Hyaline Cartilage
h. Fibrocartilage
i. Elastic cartilage
j. Connective tissue: bone
k. Connective tissue: blood
l. Skeletal muscle
m. Cardiac muscle
n. Smooth muscle
o.Neurons and Neuroglia
Here is a link where you can see the pictures of the different tissues.
