What is a cell?
 The
cell is the functional basic unit
of life which carries out the 3 vital
functions:
 Nutrition
 Interaction
 Reproduction

Are all the living things made up
of cells?

6. ALL LIVING THINGS ARE MADE UP OF CELLS

7. THE CELL
All living things are made up of
one or more cells

8. You started as one cell, then 2, 4…..
How many cells do you think you have now?

9. S XVII Robert Hooke

10. 

Hooke observed cork layers.
His microscope had 50 magnifications
(aumentos)

12. What types of cells do you know?
PROKARYOTIC CELLS
 EUKARYOTIC CELLS
 Animal cells
 Plant cells

 What is the main difference
between Prokaryotic and
Eukaryotic cells?

13. Parts of a Eukaryotic animal cell

14. The 3 main parts:

Plasmatic or cell membrane. Covers the cell.
Controls what goes in and out of the cell.

Cytoplasm. It houses all the organelles. It´s a
jelly-like substance.

Nucleus. Contains the genetic information,
controls the activity of the cells.

15. Points of the cellular theory






XIX century.
Authors: Matthias Schleiden (botanist) and
Theodor Schwann (zoologist)
All living things are made up of cells.
The cell is the functional and structural unit of
all living things
All cells come from pre-existing cells by division
Cells contain hereditary information which is
passed from cell to cell during cell division.

24. Plasmatic or cell membrane



Covers the cell
Protects it
Controls what goes in and what goes out of the
cell.

25. The cell membrane is made up of
two types of molecules: proteins and lipids

26. What else can we find in a cell?

27. Parts of a Eukaryotic animal cell

28. 






The cytoplasm
It is a jelly-like substance inside the cell.
It contains organelles. And proteins that form
the cytoskeleton.
The nucleus
It is surrounded by a nuclear membrane.
It contains the DNA, the genetic material.
It controls all the cell function´s.

30. The main organelles are:
Mithocondria
 Endoplasmic reticulum (rough and smooth)
 Golgi body
 Centrioles
 Vacuoles
 Ribosomes
 Lysosomes
 Cytoskeleton


47. TISSUE LEVEL
 What
is a tissue?
 What types of tissue can we
find in our body?

49. Which are the 4 types of tissue?
1.
2.
3.
4.
Epithelial tissue
Connective tissue
Muscle tissue
Nerve or nervous tissue

50. Epithelial tissue. Two types

Covering epithelial tissue.

Glandular epithelium..

51. 1- Covering EPITHELIAL
TISSUE
Your skin is
composed of
epithelial tissue,
and epithelial
tissue also lines
your body cavities
and major organs.

52. 1.1-Covering epithelial tissue.
Where can we find it?

Epidermis. The outer layer of the skin.

Mucosae. Covering the pharynx, mouth,
esophagus, respiratory tract…

Covering the inside part of the blood vessels.

53. 1.2- GLANDULAR EPITHELIUM
 It´s the tissue that forms the glands
 What are glands? Do you know any
examples?
 Glands secrete substances
 There are 3 types of glands:
 Exocrine glands
 Endocrine glands
 Mixed glands

54. 1-Exocrine glands
Salivary glands
 Sweat glands
 Lacrimal glands
 Liver


55.  2-Endocrine glands
Secretion of
substances that
are internally
used by the body,
e.g hormones.
-Hormones travel
through the
blood.

56. HORMONES
Adrenaline is secreted by
the suprarrenal glands.
 Strong emotions such as
fear or anger cause it to be
released into the
bloodstream.
 It causes an increase in
heart rate, muscle strength,
blood pressure, and sugar
metabolism.


57. 3- Mixed glands


They can work both as endocrine or exocrine
glands.
Example: Pancreas

As endocrine gland it produces:


INSULINE
As exocrine gland it produces:

PANCREATIC JUICE

58.  3- Mixed glands

59. 2- CONNECTIVE TISSUE
It supports the body and connects
together all types of tissue.
2.1- Conjunctive tissue
 Tendons (join the muscles
to the bones)
 Ligaments

63. 2.2Addipose tissue

Why is it neccesary?

64. 2.2- Addipose tissue
It stores fat, protects organs and
provides termic isolation

65. 2.3- Cartilage tissue

66. Cartilage tissue



Ears
Trachea
Nose

67. 2.4- Bone tissue
The major structural
and supportive
connective tissue of
the body

69. 2.5 Blood tissue

Blood components?

71. 2.5- Blood tissue
It consists
of blood
plasma,
and cell
elements,
blood cells.

72. 3- MUSCLE TISSUE

Muscles can be divided into three
main groups according to their
structure, e.g.:
 Smooth muscle tissue.
( Tejido muscular liso)
 Skeletal muscle tissue.
(Tejido muscular estriado)
 Cardiac (heart) muscle tissue.
(Tejido muscular cardíaco)

74. Where can we find?

Smooth muscle tissue.
 Dygestive
walls.

Skeletal muscle tissue:
 Skeletal

tube wall, blood vessel
muscles (they move bones)
Cardiac muscle tissue:
 Heart

75. There are
microfilaments
composed of actin
and myosin, which
are contractile
proteins.

76. 4- NERVOUS TISSUE
It detects stimuli, integrates
information and elaborates responses

77. Neurons

79. 
A neuron consists of two major parts:
1. Cell
Body. It contains the neuron's nucleus,
associated cytoplasm, and other organelles.
2. "finger-like"
projections from the cell body
that are able to conduct and transmit signals.
There are two types:


Axons - carry signals away from the cell body.
Dendrites - typically carry signals towards the
cell body.
