3. Muscular System
• It is composed of
muscle tissues.
• Muscle- Latin word
mus, meaning
mouse.
• Muscle Tissue-
consists of groups of
cells that are
specialized for
contraction.

4. Types of Muscle Tissue

5. Skeletal Muscles
• Generally attached to
bones.
• Responsible for
voluntary movement.
• Also known as
Striated muscles.

6. Smooth Muscles
• It is usually not under
voluntary control.
• Found in many
internal organs and in
the walls of many
blood vessels.

7. Cardiac Muscles
• Can only found in the
heart.
• They contract without
direct stimulation by
the nervous system.

11. Skeletal System
• Bones and their
associated tissues-
cartilage, tendons,
ligaments- make up
the skeletal system.

12. Importance of Bones

13. • Support and shape
the body.

14. • They protect the
delicate internal
organs of the body.

15. • They also provide a
system of levers (rigid
rods that can be
moved about fixed
point)

16. • Bones contain
enormous reserves
of minerals,
especially calcium
and phosphorus.

17. Structure of Bones

19. Periosteum
• Tough membrane.
• Blood vessels pass
through the
periosteum, carrying
oxygen and nutrients
to the bone.

20. Haversian canals
• Network of tubes
that contain blood
vessels and
nerves.

21. Compact Bone
• It is dense and similar
in texture to ivory.
• It is far from being
solid.

22. Spongy Bone
• Can be seen inside
the layer of compact
bone.
• It is not soft and
spongy, but actually
quite strong.

23. Osteocytes
• Deposit the calcium
salts in bone or
absorb them again.
• Responsible for bone
growth.

24. Bone Marrow
• It is a soft tissue.
• Two types of bone
marrow: yellow and
red.

25. Development of Bones

26. Cartilage
• Connective tissue.
• It does not contain
blood vessels.
• Dense and fibrous,
can support weight.
• Extremely flexible.

Age 18-20

28. Joints: Where Two Bones
Meet

29. Joints
• Joints, or places
where two bones
come together,
permit the bones
to move without
damaging each
other.

30. Immovable Joints
• Often called fixed
joints.
• Allow no movement
between bones.
• Eg. Skull

31. Slightly Movable Joints
• These joints permit a
small amount of
movement.
• Eg. Tibia and fibula;
Bones in the spinal
column

32. Freely Movable Joints
• The ends of the
bones are
covered with a
layer of
cartilage that
provides a
smooth surface
at the joint.

Endocrine System
Reproduction and Development
TOPICS

34. Endocrine System
• Other regulatory
system.
• It is composed of
glands that secrete
their products, called
hormones, into the
bloodstream.

35. Glands
• Organ that produces
a secretion, or a
substance made
inside a cell and
released from that
cell.

36. Endocrine Glands
• Only one group of
glands that produce
secretions.
• Release their
secretions directly
into the bloodstream.

37. Endocrine Glands

38. Thyroid Gland
• It produces a
hormone called
thyroxine, which is an
amino acid to which
four iodine atoms are
attached.

39. Parathyroid Glands
• Secrete a hormone
called parathyroid
hormone (PTH).
• PTH regulates the
calcium levels in the
blood.

40. Adrenal Glands
• Pyramid-shaped
structures that sit on
top of the kidneys,
one gland on each
kidney.

41. Two parts of Adrenal Glands
ADRENAL CORTEX
• Outer part.
• It produces corticosteroids
and aldosterone..
ADRENAL MEDULLA
• Inner part.
• It produces adrenaline and
noradrenaline.

42. Reproductive Glands
Gonads
Ovaries
Estrogen
Progesterone
Testes Androgens

43. Pancreas
• Most unusual gland.
• Produces pancreatic
fluid, which leaves the
pancreas by means of
a duct and empties
into the digestive
system.

44. Pituitary Gland
• A bean-sized
structure that dangles
on a slender stalk of
tissue at the base of
the skull.

45. Two parts of Pituitary Gland
Posterior Pituitary
• Antidiuretic
hormone (ADH)
• Oxytocin
Anterior Pituitary
• Follicle-stimulating hormone (FSH)
• Luteinizing hormone (LH)
• Thyroid stimulating hormone (TSH)
• Adrenocoticotrophic hormone (ACTH)
• Somatotropin
• Prolactin
• Melanocyte-stimulating hormone
(MSH)

46. Hypothalamus
• It controls the secretions
of the pituitary gland.
• Aside from pituitary gland.
It is also a major area
where the nervous system
and the endocrine system
interact.

Skin System

48. Skin System
• Provides protection for
the external part of the
body and must maintain
its protective function
for the protection and
survival of the cells.
