Pregunta 1
Pregunta
What is an articulation?
Respuesta
-
Where two bones meet at a joint.
-
A pivot point.
-
Cartilaginous ends moving against each other.
Pregunta 2
Pregunta
Soft tissue in joints has no organic component.
Respuesta
- True
- False
Pregunta 3
Pregunta
Choose the FALSE statement about cartilage.
Respuesta
-
Cartilage is soft tissue.
-
Hyaline cartilage is the same as articular cartilage.
-
Fibrocartilage is what the epiphyseal plate is made from.
-
Fibrocartilage has a different histological structure from hyaline cartilage.
Pregunta 4
Pregunta
Choose the correct statements about cartilage histology.
Respuesta
-
The chondrocytes live in lacunae.
-
Cartilage is composed mainly of collagen fibres.
-
Cartilage is white due to fatty acids.
-
Cartilage acquires nutrients via diffusion as it is not vascular.
Pregunta 5
Pregunta
Diffusion of nutrients into cartilage is achieved via 'loading', regular joint movement/activity
Respuesta
- True
- False
Pregunta 6
Pregunta
Hyaline cartilage is [blank_start]amorphous[blank_end], with [blank_start]little[blank_end] collagen content, and a [blank_start]high[blank_end] water content, that resists [blank_start]compression.[blank_end]
Fibrocartilage has [blank_start]many[blank_end] bundles of collagen, and resists [blank_start]tension.[blank_end] The orientation of these fibres are aligned in the direction of stress and so it also resists [blank_start]compression[blank_end], making it specialised.
Respuesta
-
amorphous
-
little
-
high
-
compression.
-
many
-
sparse
-
tension.
-
compression
-
tension
Pregunta 7
Pregunta
Lack of bony congruence is made up for by hyaline cartilage moulding to the articulations of synovial joints.
Respuesta
- True
- False
Pregunta 8
Pregunta
Hyaline cartilage remodels.
Respuesta
- True
- False
Pregunta 9
Pregunta
The more bony congruence there is, the more soft tissue support is needed.
Respuesta
- True
- False
Pregunta 10
Pregunta
The menisci are convexly shaped and diffuse forces through the bones of the knee.
Respuesta
- True
- False
Pregunta 11
Pregunta
Choose the incorrect statement.
Respuesta
-
Intervertebral discs are made of fibrocartilage.
-
The nucleus pulposus is a gel like structure which resists compression, and is distributed over the top of the intervertebral disc.
-
"Slipping a disk" is a tear in the fibrocartilage of the intervertebral disc where the nucleus pulposus has been removed from the proper position.
Pregunta 12
Pregunta
Choose the correct statements about ligaments and tendons.
Respuesta
-
They are composed of DFCT.
-
They have low collagen content.
-
They are slightly vascularised.
-
They are maintained by fibroblasts.
-
Ligaments join muscle to bone at an insertion, facilitating movement.
-
Tendons join bone to bone, restricting unwanted movement.
Pregunta 13
Pregunta
A lateral ligament will restrict adduction.
Respuesta
- True
- False
Pregunta 14
Pregunta
When a tendon is pulled out it usually takes a section of bone with it.
Respuesta
- True
- False
