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

38

What do joints have

rich blood and nerve supply
