Question
|
Answer
|
|
The head of condyle articulates
with |
Articular tubercle and anterior
part of mandibular fossa |
|
The mandibular fossa is in
|
Temporal bone
|
|
The articular surfaces of
mandible and temporal bone is interposed by |
Articular disc
|
|
The anterior region of
articular disc fuses with |
Fibrous capsule
|
|
The posterior region of
articular disc fuses with fibrous capsule by |
Bilaminar zone
|
|
The loose connective attachment
at the posterior border of articular disc facilitates |
Anterior movement
|
|
The medial and lateral surface/
corners of articular disc are attached to |
Condyle of mandible
|
|
The articular space can be
divided in to |
Lower condylodiscal and upper
temporodiscal compartments |
|
In saggital section the shape
of the articular meniscus is |
Biconcave
|
|
The vasuclarization of
bilaminar zone of the posterior band of the articular disc is |
Richly vascularized and
innervated |
|
The superior stratum of
bilaminar zone of the posterior band of the articular disc is attached to the |
Posterior wall of mandibular
fossa; Squamoustymapanic suture |
|
The inferior stratum of
bilaminar zone of the posterior band of the articular disc is attached to the |
Mandibular condyle
|
|
The rotational movement of the
Temporomandibular joint occurs in |
Inferior portion
|
|
The rotational movement across
an axis through heads of condyle of Temporomandibular joint results in |
Opening of jaws
|
|
The translatory movement of
articular disc results in |
Anterior and Posterior movement
of jaws |
|
The articular capsule is
strengthened by |
Lateral ligament
|
|
The inner aspect of the
Temporomandibular joint capsule is lined by |
Synovial membrane
|
|
The synovial membrane does not
line |
Surface of disc; Articular
tubercle; Condylar head |
|
The indication of a
Temporomandibular joint is seen at the ________ week of embryo. |
Tenth
|
|
In embryo, Temporomandibular
joint cavities appear around the |
Twelfth week
|
|
The condyle of mandible is made
up of |
Cancellous bone covered by thin
compact bone |
|
The trabeculae at the condylar
head radiate from neck and meets the cortex at |
Right angle
|
|
With increase in age,
trabeculae of the condyle |
Thickens
|
|
A layer of hyaline cartilage
under the fibrous covering of head of condyle indicates |
Period of active growth
|
|
The roof of mandibular fossa is
made of |
Thin compact bone
|
|
The articular tubercle is
composed of |
Cancellous bone covered by thin
compact bone |
|
The articular fibrous
connective tissue of an adult contains varying number of |
Chondrocytes
|
|
The number of chondrocytes in the articular fibrous
covering of Temporomandibular joint |
Increases with age
|
|
The fibrous connective tissue
lining the posterior articular tubercle has |
Three zones
|
|
The inner zone of the fibrous
covering posterior articular tubercle has fibers at |
Right angles to bone
|
|
The blood supply in central
area of articular disc is |
Devoid of blood supply
|
|
Temporomandibular joint can be
best described as a |
Ginglymo arthroidal synovial
joint |
|
According to phylogenetics the
primary jaw joint in the humans is the |
Incudomalleolar articulation.
Temporomandibular joint is a secondary joint in phylogenetics as the joint from the Meckel’s cartilage is the Incudomaleolar joint |
|
The type of collagen elaborated
by the chondroblast in condylar cartilage during formation of the condyle is the |
Type II collagen
|
|
At birth the articular eminence
is |
Not formed
|
|
The fan shaped ligament
associated with the Temporomandibular joint is the |
Temporomandibular ligament
|
|
The residual perichondrium of
Meckel’s cartilage is present as |
Sphenomandibular ligament
|
|
The free border of deep
cervical fascia is represented by the |
Stylomandibular ligament
|
|
The folds or the microvilli in
the synovial membrane |
Increases with age. The folds
of the synovial membrane increases with age and in pathology. |
|
The first indication of the
Temporomandibular joint is the formation of the |
Temporal blastema. After the
temporal blastema is formed, condylar blastema is formed in mesenchymal condensation. |
|
The fibrous layer covering
condyle is lined by a vascular fibrous connective tissue is the |
Lamina splendens
