A) Know the four basic tissues, how they differ, and what their general functions are

B) Understand the difference in function between flat and cuboidal/columnar epithelial cells

C) Know the basic components of connective tissue

D) Understand how adjusting the amounts of collagen, elastin, and different kinds of ground substances affects the function of connective tissues

Solution

A) epithelial tissue- originated from ecto, meso and endodermis.

Function: protection, covering , secretion and excretion.

Connective tissue- originated from mesoderm

Function : connection, support, blood production and defense mechanism.

Muscular tissue- originated from mesoderm

Function: movement and locomotion.

Nervous tissue- originated from ectoderm

Function: control and coordination.

B).Flat or squamous epithelium is involving in filtration and diffusion , columnar / cuboidal epithelium is involving in absorption, secretion and excretion

C) basic components of connective tissue include connective tissue fibres, connective tissue cells and connective tissue matrix.

D)collagen ,elastin and reticulin involves the maintenance of regidity, toughness or elasticity of connective tissue. In different connective tissues different amounts of these protein play role
