2) musculature attaching the skull, cervical region, and upper thorax together develops 3) the head is held upright
4) the intervertebral disc height becomes greater anterior than posterior.

118
Q

what is the name given to the integration of visual and motor pathways associated with holding the head erect?

A

the righting reflex

119
Q

what developmental events are indicated in the formation of the adult lumbar curve?

A

1) crawling will cause the abdomen to put tension on the lumbar region and pulls it forward.
2) muscle development is promoted to compensate for the swayback of the lumbars
3) intervertebral disc height will become greater anterior compared to posterior
4) walking will further promote muscle and intervertebral disc development

120
Q

what developmental events are indicated in the formation of the adult cervical curve?

A

1) centers for vision and equilibrium will appear in the brain
2) musculature attaching the skull, cervical region, and upper thorax together develops 3) the head is held upright
4) the intervertebral disc height becomes greater anterior than posterior.

121
Q

what is the relationship between curve direction and handedness?

A

a right handed person has a high probability ofr a right thoracic, left lumbar curve combination

122
Q

what clinical examples of abnormal curvatures along the vertebral column were stressed in class?

A

military neck, humpback or hunchback, and swayback

123
Q

what are the curve clasifications for military neck?

A

a kyphosis or hypolordotic curve

124
Q

what are the classifications of scoliosis according to the scoliosis research society?

A

magnitude, location, direction, etiology, and structural/non-structural

125
Q

what does idiopathic scoloiosis infer?

A

the scoliosis is unique to the individual, it has no known cause, unknown etiology

126
Q

identify the curve direction, location, gender bias, and incidence of infantile idiopathic scoliosis

A

left thoracic, male, less than 1% incidence

127
Q

identify the curve direction, location, gender bias and incidence of juvenile idiopathic scoliosis

A

right thoracic, females over 6 years old, 12%-21% incidence

128
Q

identify the curve direction, location, gender bias and incidence of adolescent idiopathic scoliosis

A

right, thoracic, or right thoracic and left lumbar, females, 80% incidence

129
Q

what is the relationship between curve deviation, incidence, and the more likely to worsen?

A

the greater the deviation, the lower the incidence, and the more likely to worsen

130
Q

which subdivision of the iliocostalis muscle appears to have a reversal of origin - insertion?

A

iliocostalis lumborum pars lumborum

131
Q

which muscle group is innervated by both dorsal rami and ventral rami of spinal nerves?

A

intertransversarii

132
Q

the semispinalis capitis and spinalis capitis may fuse to form what muscle?

A

biventer cervicis

133
Q

identify all muscle groups innervated by dorsal primary rami branch patterns

A

1) splenius
2) erector spinae
3) transversospinalis
5) suboccipital
6) interspinalis
7) levator costarum
8) intertransversarii

134
Q

which muscle is said to form the iliolumbar ligament

A

quadratus lumborum

135
Q

based on the density of muscle spindles, what is the proposed function of the intertransversarii?

A

acts as a proprioceptive transducer in conjunction with interspinalis to corrdinate the smooth movement of the spine and to maintain appropriate posture

136
Q

what is the proposed function of the suboccipital muscle group?

A

postural stabilizers of the atlanto-occipital adn atlanto-axial joints

137
Q

which muscles of the spine exhibit a reversal of the expected origin - insertion combination?

A

iliocostalis lumborum pars lumboru, longissimus thoracic pars lumborum and multifidis lumborum

138
Q

which muscles are identified as transversospinalis muscles?

A

semispinalis, multifidis, and rotators

139
Q

which transversospinalis muscle attaches to articular and mammillary processes along the spine?

A

multifidis

140
Q

what is the vertebral column origin for the longissimus thoracis pars lumborum?

A

posterior superior iliac spine (PSIS) of the innominate bone
