Types of tissue

Question 1

Name the four broad categories of tissues found in the human body.

Answer 1

Epithelium tissue, Connective tissue, Muscular tissue, Nervous tissue

Question 2

Group of similar cells that typically have a common embryonic origin and
function together to carry out specific activities

Answer 2

Tissues

Question 3

Functions of Epithelial Tissue

Answer 3

• Covers body Surface
• Interaction btwn the body internal and external
  environment
  -provides protection

Question 4

Functions of Connective Tissue

Answer 4

• Binds organ together
• Stores energy as fat
  -Provides immunity
• Provides structural
  support
• Has wide variety of tissue such as bone and blood

Question 5

Functions of Muscular Tissue

Answer 5

• Contraction and force
  generation
• Generates body heat
• Faciltate the movement of fluid e.g blood passing through the veins

Question 6

Functions of Nervous tissue

Answer 6

• Able to detect changes within the internal and external providing electrical signals
• It activates the muscular contraction and glandular secretions.

Question 7

What are Cell junction

Answer 7

This are contact point btwn the plasma membrane which holds the cell tightly together.

Question 8

What is Tight junction all about?

Answer 8

Tight juction is a weblike strand of transmembrane protein which help seals the cell to avoid leakage to happen.

Question 9

Provide strong mechanical attachments between cells using plaque of actin filaments

Answer 9

Adherence Junction

Question 10

What is Desmosomes

Answer 10

It is an anchor cell together with the help of intermediate filament, that helps bring strucutural stability btwn the cells and tissue

Question 11

Attach cells to the basement membrane, linking the cell to underlying structures

Answer 11

Hemidesmosomes

Question 12

Allows communication between cells by permitting the passage of ions and small molecules. Connexins (a type of membrane protein) form fluid- filled tunnels called connexons that connect neighboring cells, allowing ions and small molecules to diffuse freely between them

Answer 12

Gap Junctions

Question 13

A germ layer which has Neurons, Anus, skin cells, pigment of cells, how is it called

Answer 13

An Ectoderm

Question 14

A germ layer which contains Cardiac Muscle, Skeletal Muscle, Tubule Cell of Kidney,Red Blood cells, Smoth muscle

Answer 14

Mesoderm

Question 15

A germ cell that has lung cell, thyroid and pancreatic is known as

Answer 15

Endoderm

Question 16

The single cell which is formed by the fusion of an egg and sperm, that undergoes rapid mitotic divisions after fertilization, leading to the formation of an embryo

Answer 16

Zygote

Question 17

Able to differentiate into any cell type and potentially develop into a complete organism.

Answer 17

Totipotent

Question 18

The Nervous tissues primarily originates through the

Answer 18

Ectoderm

Question 19

The Muscle tissues originates through

Answer 19

Mesoderm
