Slide 8 - Diapositive
Your nervous system is your bodies fast communication system:
Your CNS - Central nervous system (control system)
Your PNS - Peripheral nervous system (routers)
Nervous System
Slide 9 - Diapositive
When your body observes stimuli from it's environment, the following cycle happens:
PNS - Your body receives a stimuli (senses)
CNS - Your brain/spinal cord coordinates a response.
PNS - Muscles / glands create a response
Signals
Slide 10 - Diapositive
Signals
Slide 11 - Diapositive
Our body has 3 types of neurones:
sensory neurones - connects senses to the CNS
interneurones - the neurones within the CNS
motor neurones - connects the CNS to the effectors
Neurones - Wires
Slide 12 - Diapositive
Our skeleton is an important part of our body, it consists of 206 bones.
Bones are made out of hard bone and cartilage.
Hard bone (with calcium) makes it stronger
Cartilage makes it more flexible
When you get older your bones will have less cartilage
What is a skeleton?
Slide 13 - Diapositive
Our skeleton has 4 very different but very important jobs to help us survive:
support
movement
protection
blood production
The functions
Slide 14 - Diapositive
Many organisms look completely different from each other and they have many different types of skeletons:
endoskeleton
exoskeleton
hydroskeleton
Types of skeletons
Slide 15 - Diapositive
JOINTS
A joint is a place where two bones meet. This is also the place where your skeleton can move.
Slide 16 - Diapositive
TYPES OF JOINTS
Fixed -
no movement, skull
Ball and socket-
movement in all directions, hip/shoulder
Hinge-
movement in 1 direction, elbow/knee
Pivot-
turning movement, radius+ulna/neck
Gliding-
glide over each other, wrist/backbone
Slide 17 - Diapositive
PART OF A JOINT
Ligaments: connect bone to bone
Tendon: connect bone to muscle
Synovial joint: ball and socket, hinge, pivot. Also have synovial fluid to oil the joint
Slide 18 - Diapositive
MUSCLES
Muscles can work in antagonistic pairs, because muscles can only pull or relax. They need a partner (antagonist) to move the opposite way
Slide 19 - Diapositive
Complete them in the Google docs.
You are not allowed to share the document and work together.
Your need to have it completed & submitted before the next lesson.
