Question 1

Cell

Answer 1

he basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.

Question 2

Type of Cells

Answer 2

Epithelial, Nerve, Muscle, Connective Tissue

Question 3

Function of the cell

Answer 3

• The cell provides support and structure to the body.
• It facilitates growth by mitosis.
• It helps in reproduction.
• Provides energy and allows the transport of substances.

Question 4

Epithelial Cells

Answer 4

• cover the inner and outer linings of body cavities, such as the stomach and the urinary tract
• diffusion, filtration, secretion, selective absorption, germination, and transcellular transport.

Question 5

Nerve Cell

Answer 5

The basic unit of communication in the nervous system

Question 6

Nerve cell is also called

Answer 6

Neurons

Question 7

3 Type of Neurons

Answer 7

Sensory, Motor, Interneurons

Question 8

Muscle Cells

Answer 8

• also known as myocytes (ma-yo-sayts)

- the cells that make up muscle tissue.

Question 9

Function of Muscle Cells

Answer 9

Muscle cells are specialized to contract, i.e. create a pulling force to stabilize or move parts of the body.

Question 10

3 Types of Muscle Cells

Answer 10

Cardiac, Skeletal, Smooth

Question 11

Cardiac Muscle (myocardium)

Answer 11

• makes up the thick middle layer of the heart.
• ## surrounded by a thin outer layer called the epicardium

Question 12

Characteristics of Cardiac Muscle

Answer 12

• they are involuntary and intrinsically controlled, striated, branched, and single nucleated.
• Cardiac muscle is considered to be an involuntary tissue because it is controlled unconsciously by regions of the brain stem and hypothalamus.

Question 13

Skeletal Muscle

Answer 13

• comprise 30 to 40% of your total body mass
• they’re the muscles that connect to your bones and allow you to perform a wide range of movements and functions
• skeletal muscles are under our conscious control, which is why they are also known as voluntary muscles. Another term is striated muscles, since the tissue looks striped when viewed under a microscope.

Question 14

Functions of Skeletal Muscle

Answer 14

Skeletal muscles maintain posture, stabilize bones and joints, control internal movement, and generate heat.

Question 15

Smooth Muscle

Answer 15

• an involuntary non-striated muscle

- It is in the stomach and intestines where it helps with digestion and nutrient collection.

Question 16

Connective Tissue

Answer 16

• tissue that supports, protects, and gives structure to other tissues and organs in the body.
• also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue.
• is made up of cells, fibers, and a gel-like substance.

Question 17

Types of Connective Tissues

Answer 17

BLOOD, BONE, CARTILAGE, CONNECTIVE TISSUE PROPER.

Question 18

Cells are made up of

Answer 18

nucleic acids, proteins, carbohydrates, and lipids.

Question 19

2 Main Types of Cells

Answer 19

prokaryotic cells and eukaryotic cells.

Question 20

Primary Cell of Connective Tissue

Answer 20

fibroblast. Its function is to produce and maintain the ECM of connective tissue.

Question 21

Cartilage

Answer 21

is the avascular connective tissue that connects bones at joints and comprises walls of upper respiratory airways and external ear.

Question 22

3 Types of Cardilage

Answer 22

Hyaline cartilage - most represented type. Rich in collagen II molecules

Elastic cartilage - has many elastic fibers. It is found in the walls of the external

Fibrocartilage - has many collagen I molecules.

Question 23

Prokaryotic Cell

Answer 23

a type of cell that does not have a true nucleus or membrane-bound organelles.

Question 24

Eukaryotic Cell

Answer 24

The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes cell

Question 25

Cells are also called

Answer 25

basic unit of life
- The basic needs for the survival of all living organisms are the same. All living organisms need to respire, digest food for obtaining energy, and get rid of metabolic wastes.
