Axial skeleton - what is it made up of?
How many vertebrae/ bones in spinal column?
Sections & numbers
33 vertebrae / bones:
- Cervical - 7 bones
- Thoracic - 12 bones
- Lumbar - 5 bones
- Sacral (sacrum) - 5 fused bones
- Coccygeal (coccyx) - 3-4 fused bones
Cervical / Thoracic/ lumbar - think Breakfast (7), Lunch (12), Dinner (5)
Ribs -
No. of?
Also called what?
What relationships do the ribs have with the Thoracic spine?
12.
Also called ‘costals’
12 ribs = 12 Thoracic spine vertebrae.
The ribs form joints meeting at the Thoracic spine.
Why is the Thoracic spine less mobile?
Because the ribs are there too = less space
And because there is less space between each vertebrae in the thoracic spine.
Axial skeleton - how remember what it is?
Like ‘axis’ - consists of the bones that are towards the center of the body…
Head
Spinal column
Sternum
Ribs
Appendicular skeleton
What are its 2 parts?
Upper extremities
Lower extremities
(Think appendages)
Appendicular skeleton - Upper extremities
Consists of what?
Appendicular skeleton - Lower extremities
Consists of what?
The pelvis consists of 2 halves
What are these called?
And how many bones makes up each half / what are they called?
PELVIS = OS COXAE
Each half has 3 FUSED BONES
- illium
- ischium
- pubis
The 3 bones that make up each half of the pelvis..
Name and describe them.
3 Fused bones make up each half of the pelvis.
What is the upper leg / thigh bone called?
Femur.
What are the 2 lower leg bones called?
TIBIA -
- Front of lower leg (shin)
- On the inside (medial) of the fibula.
- Is weight bearing.
FIBULA
- Think Fib = Lie = L = La
- Is on the outside (lateral) of the lower leg
Where abouts is the lateral malleolus when standing?
(and what is it?)
Lateral malleolus is the outer ankle bone and is at the end of the Fibula.
It is a little bit posterior (behind) and inferior (below) to the medial malleolus
Medial malleolus = inside ankle bone, at the end of the tibia. Tibia = shin bone)
What is the kneecap called.
The Patella.
What are the bones in the ankle area of the foot called?
And how many are there?
Tarsals.
7 bones - where the ankle + heel meet.
What are the bones across the front of the foot called?
Meta tarsals.
5 of them. Connect the tarsals to the Phalanges.
What are the bones in the toes called
Phalanges.
What 2 things are boney landmarks important for?
Postural alignment
Muscle attachment
What are the key Postural bones landmarks?
6 of them.
1) ANTERIOR SUPERIOR ILIAC SPINE
- (ASIS)
- At the front/upper of pelvis
2) PUBIS SYMPHYSIS
- (PS)
- Where the 2 pubis bones meet in the middle
3) ISCHIAL TUBEROSITY
- Sit bones
- At the bottom of the ischium bone
4) GREATER TROCHANTER OF FEMUR
- At the top of the femur
5) LATERAL MALLEOLUS OF FIBULA
- Outer ankle bone
- At the end of Fibula
(Think lateral = L = fibula)
6) MEDIAL MALLEOLUS OF TIBIA
- Inner ankle bone
- At the end of Tiibia
What is the bonesy landmark at the front & top of the Pelvis called?
ANTERIOR SUPERIOR ILLIAC SPINE
(ASIS).
What is the boney landmark where the 2 pubis meet in the middle called?
PUBIC SYMPHYSIS
(PS)
What is the proper name for the boney landmark we call the sit bones
ISCHIAL TUBEROSITY
How do you find your sit bones?
Sat down…
If rock too far back off the sit bones you will be a little slouched in posture
If rock too far in front of them you will be in hyper lordotic posture
When we are sat right on top of them it helps us to find neutral spine
What is the greater trochanter, where is it and what is it designed for?
It is a boney landmark - large boney protrusion
Located at the top of the femur (thigh bone).
Designed for a lot of muscle attachment.
To find on self - take hands to side of hips and take a couple of squats. Move fingers around until you find the point you are.pivoting on each time you you squat - this is the greater trochanter.
If you go to the top of the greater teochanter and go inwards towards the midline of the body, that is where the hip joint lies.
