1
Features of anatomical position
Head facing forwards, standing upright, upper limbs by sides, lower limbs straight etc
2
Cross show anatomy always shows
inferior
3
what is a joint
Union between two or more rigid components
4
Rigid components in joints
Bones or cartilage
5
how many rigid components needed in a joint
can be more than two
6
Why do we need joints
Movement and growth
7
Types of joints
Fibrous
Cartilaginous
Synovial
8
What are fibrous joints
dense fibrous connective tissue
9
what are fibrous tissues under tension
strong
10
Sultures
fibrous joints between flat bones
11
syndesmosis
slightly movable fibrous joint in which bones such as the tibia and fibula are joined together by connective tissue
12
Cartilaginous joints
layers of cartilage inbetween bones
13
Two types of Cartilaginous joints
Synchondroses (primary)
Symphyses (secondary)
14
Synchondroses (primary)
Allow for bone growth in long bones
15
what disappears in adults
Synchondroses joints
16
How many types of cartilage does Synchondroses have
one
17
what happens to Synchondroses joints
eventually ossify
18
What cartilaginous joint doesn't ossify with age
Symphyses
19
where is Symphyses located
between the left and right pubic bones near the midline of the body
20
What offer a little bit movement Symphyses or Synchondroses joints
Symphyses
21
what are Intervertebral discs made of
fibrocartilage
22
function of a Intervertebral disc
act as a shock absorber, keeping vertebrate separate
23
where is Intervertebral disc found
in-between vertebrae in the spinal column
24
what is Articular cartilage
the smooth, white tissue that covers the ends of bones where they come together to form joints
25
Articular cartilage made of
hyaline cartilage
26
What offers greatest movement
synovial joints
27
Synovial joints also contain
Articular discs
Ligaments
Bursae
28
Different synovial joints
Hinge, ball & socket, pivot, plane, saddle, and condylar
29
Lower limb compared to upper limb
more rotation in medial direction
30
extension and flexion
different movements in upper and lower limbs
31
Joint stability dependant on
Shape of articulating surfaces
Fibrous capsule & ligaments
Muscles
32
anastomoses
lots of branching of blood vessels, following different paths
33
Proprioception
body awareness without looking
34
what is Hilton’s law
The nerve supplying a muscle that crosses a certain joint, also innervates this joint.
35
Joint pathologies
Trauma
Arthritis
Craniosynostosis
36
what is Craniosynostosis
abnormal deformed skull growth that nerves can comprehend due to increased pressure within the skull
37
symptoms of Craniosynostosis
persistent headaches, learning difficulties, eye problems etc
