Protection, Support & Locomotion Systems

Ch 34 Guide &

Intro to Coordination Systems

coordination systems systems that physically and chemically coordinate the body
Physical:

SKIN

SUPPORT

MUSCULATURE

Chemical:

NERVOUS

ENDOCRINE

COORDINATION SYSTEMSSystems that Physically and Chemically coordinate the body:
systems multiple organs working together to serve a body function
SYSTEMS: Multiple organs workingtogether to serve a body function
  • Tissues: cells working together to do a simple function
  • Organs: tissues working together to do a complex function
  • Cells: smallest basic units

Respiratory system

systems are made of organs tissues cells connective tissues
Systems are made of: Organs, Tissues, Cells,& connective tissues

Tissues include:

a. Epithelial tissue

b. Muscle tissue

c. Connecting tissue

1) Cartilage

2) Tendons

3) Ligaments

Smoker’s Lung Tissue

the skin 1 structure
The Skin: 1. Structure……….

a. Epidermis made of

  • epithelial cells

b. Dermis with

  • sweat glands
  • hair follicles
  • oil glands
  • capillaries
  • nerve cells
a the skin the largest organ in the body
A. The Skin..……….. the largest organ in the body

2. Function:

  • protection
  • temperature control
  • sensory
  • integrity of the body
  • secretions from glands
  • produces Vitamin D
support systems may be
Exoskeleton:

Endoskeleton:

Support Systems may be:

Internal set of bones

Hard outer covering

exoskeletons
Exoskeletons
  • Hard outer covering
  • made of chitin or shell
  • examples:

lobster, snail, squid

Does the starfish have and exoskeleton ?

no an endoskeleton
No !.. An Endoskeleton:

Made of

  • 1). cartilage or
  • 2). bone

Covered by

  • muscles
  • skin

Examples: starfish, shark, mammals.

b1 human endoskeleton made of
B1. Human Endoskeleton made of

Boo !

  • Axial: skull, backbone, ribs, sternum
  • Appendicular: arms, legs, shoulders, hips,wrists, ankles
endoskeletons also have
Endoskeletons also have…….

1c. Ligaments that hold bone to bone

1d. Tendons that hold muscle to bone, “muscle tenders”

1e. Joints where 2 bones come together

b3 the support system functions
B3. The Support System Functions:
  • Protection of organs
  • Movement
  • Stores calcium & potassium
  • Produces RBC (marrow)
  • Supports
c1 three types of muscle
C1.Three types of Muscle:
  • A. Smooth: involuntary control of internal organs for digestion, & blood vessels
  • B. Cardiac: involuntary control of the heart
  • C. Skeletal: Voluntary control of the skeletal muscles for movement
the musculature system
The Musculature System……..

2. Structure:

  • Voluntary Muscles

Striated-Skeletal

  • Involuntary Muscles

Cardiac- Heart

Smooth-Stomach

Striated Skeletal

Several nuclei

Box shaped, many mitochondria

cardiac muscle
Cardiac Muscle:
  • Fewer Striations
  • Fewer Mitochondria
  • Large nuclei
  • Lattice work of spaces between some cells
  • Still square shape
  • One nuclei per cell
smooth muscle
Smooth Muscle:
  • Eye shaped
  • One nuclei per cell
  • No lattice work
  • No striations
  • Long & drawn out
  • Fewer Mitochondria
how do muscles contract
How Do Muscles Contract?

Muscle bundles work in opposite pairs:

Contracting & Relaxing

(biceps & triceps in the arms)

4a sliding filament theory of musclecontraction
4a. Sliding Filament Theory of MuscleContraction:

Relaxed Muscle

Actin

Muscles are made of

  • Bundles
  • Of fiberswith
  • Smaller subunits ofmyofibrils

Myofibrils are made of

  • Actin & Myosin chemcials
  • require ATP energy
  • To slide past each other

Myosin

Contracted Muscle

c6 musculature system function
C6. Musculature System Function:
  • Movement
  • Stores Protein
  • Maintains Body Shape
