The movement of the TMJ in transverse direction occurs at?
Superior joint compartment
The TMJ meniscal disc has the following description, except?
The thinnest part is at the anterior compartment
Metopic suture is associated with what bone?
Frontal bone
The sphenoid bone develops from
Endochondral development
Pterion comprises of the following
Sphenoid, temporal, frontal, parietal
The number of muscle present in man
640
The 5th muscle of mastication is
Sphenomandibularis
A segment of the lung that is pyramidal in shape, apex
towards the lung root
Bronchopulmonary segment
It is much easier to smile because when you smile there are 20 muscles that act on it, but when you frown there are how many muscle acts on it?
40 muscles
This muscle is also called caninus
levator labii superioris
It extends the arm and medially rotates the glenohumeral
joint
subscapularis
Superficial muscle that covers the lower jaw and anterior
part the neck, what is the nerve supply of this muscle
Cervical Nerve
The main blood supply of the 2nd and 5th digits when
blocked or injured will cause
tunnel syndrome
The muscles of the thigh that is located at the lateral
compartment moves the thigh in
away from the midline
A linear depression that crosses the mesial marginal
ridge of maxillary premolar occlusally
Mesial marginal developmental groove
The sixth cusp of mandibular 1st molar located between
the two lingual cusps is:
Tuberculum intermedium
The first evidence of calcification of maxillary third molar:
7 to 9 years
The largest incisal/occlusal embrasure is located between:
Maxillary lateral incisor and canine
A peg shaped lateral incisor would developed from how many
lobes?
Two lobes
The height of contour of a mandibular incisor when viewed facially
is located at what third of the crown?
Incisal
Which among the permanent teeth has its mesial marginal ridge
Mandibular first premolar
The repeating units of nucleic acids or nucleotides are made up of the following molecules
pyrimidine/purine ,
sugar and phosphate
In the cytoplasm, rRNA and protein combine to form a
nucleoprotein
The synthesis of specific proteins from the mRNA base sequence
translation
This type of RNA is characterized by bending on itself to form a cloverleaf structure that twists further into an upside down “L” shape is
tRNA
Transmembrane proteins of opposite cells attach in a tight zipper-like fashion are seen in
desmosomes
This type of RNA carries the genetic code to the cytoplasm for controlling the type of protein formed
mRNA
During this stage of mitosis, the 2 chromatids of each chromosome are pulled apart at the centromere and all 46 pairs of chromatids are separated forming two separate sets of 46 daughter chromosomes
telophase
When cells are no longer needed or become a threat to the organism, they undergo a suicide programmed cell death called
apoptosis
The transport of glucose molecules from outside the cell, across the membranes, and into most tissue cells (excluding the intestine
or kidney tubule) occurs by the process of
facilitated diffusion
This type of contraction/s is/are propagated for only short distances and function to mix intestinal contents
peristalsis
The only means by which macromolecules, such as protein molecules can enter cells is by
pinocytosis
This structure serves as the site and carries the enzymes for protein synthesis
ribosomes
These are glycoproteins and/or glycolipids on extracellular surface
which serve as ID tags to determine which species, which type of cell, or individual are the
cell recognition proteins
These are subtypes of transport proteins which bind to a substance
and carry it across the membrane, can change in shape in the process are the
integrins
Third stage of tooth eruption.
Gingival Emergence
The tooth is pushed out of the bone by forces generated
beneath and around the tooth
Remnants of dental lamina and connective tissue contained in the gubernacular canal which are found in
gubernacular
cord
Cells within the periodontal ligament which may generate an eruptive force either by their contractility
or locomotor activity.
fibroblasts
Mandibular arch conforms generally to one or more curved planes which appear concave and the opposing maxillary arch, the curvature appears
convex
Development of occlusion begins with the occlusion of the
deciduous teeth
Used to describe contacts between the teeth in opposing dental arches during mandibular movements
Articulation
Curved alignment of cusps and incisal ridges observed from a point opposite the first molars.
Curve of Spee
Position assumed by the permanent tooth germs relative to their precursor.
lingual
Temporomandibular joint is composed of muscles, bone, ligament,
cartilage and
synovial membrane
Bony elevation located anterior and posterior to the glenoid fossa
articular eminence
Olfactory receptors are located on the olfactory mucous which lies on the
posterodorsal part of nasal cavity
The pterygomandibular raphe is a tendon between which muscle?
buccinator and superior constrictor
The longest and most convoluted portion of the digestive tract
is:
Small intestine
Common opening of the common bile duct and the pancreatic duct in the duodenum:
Common bile orifice
In performing tracheostomy, the involved triangle is the:
Muscular triangle
Inner layer of the dura mater between cerebral hemispheres cerebellum:
falx cerebri
Indentation in the medial border of the kidney’s for the passage of renal vessels and ureters:
renal hilus
Which chamber of the heart receives blood from the superior and inferior venae cavae and also from the anterior cardiac veins?
Right atrium
Which lobe of the cerebrum is responsible for hearing?
Temporal lobe
Non-neuronal tissue of the CNS that performs supportive and other ancillary functions is called:
Neuroglia
The cardiac notch is a deep indentation on the:
Superior lobe of the left lung
During an inferior alveolar block injection, the needle passes through the mucous membrane and the buccinator muscle and lies
lateral to which muscle?
Medial pterygoid
Which among the permanent molars develops from 5 lobes?
mandibular 1st
The lingual lobe of an anterior teeth is referred to as the:
cingulum
Mesial developmental depression is a characteristic feature of
which premolar?
maxillary 1st
During a working side movement of the mandible, the oblique ridge of a maxillary first molar passes through which sulcus of a permanent mandibular first molar?
Distobuccal sulcus
