Q

Which of the following sutures is correctly matched with its landmark?a) Inion - midpoint on posterior margin of foramen magnumb) Bregma - junction of sagittal and coronal suturesc) Opisthion- junction of sagittal and lamboidal suturesd) Lambda - prominent part of the external occipital protuberance.

A

b) Bregma - junction of sagittal and coronal suturesBelow are the correct pairings!Opisthion - midpoint on posterior margin of foramen magnumBregma - jxn of sagittal and coronal sutures** Lambda - jxn of sagittal and lamboidal sutures**Inion - prominent part of the external occipital protuberance.

Q

Which of the following sutures is correctly matched with its landmark?a) Asterion- smooth prominence on frontal bone between and above the eyebrowsb) Pterion - meeting of frontal, parietal, sphenoid, and temporal bonesc) Nasion- junction of lambed suture, OM suture and parietomastoid sutured) Glabella - junction of frontal and nasal bone sutures

A

b) Pterion - meeting of frontal, parietal, sphenoid, and temporal bonesCorrect pairings below:- Glabella: smooth prominence on frontal bone between and above the eyebrows (close to mitopic suture)- Pterion: meeting of frontal, parietal, sphenoid, and temporal bones- Asterion: junction of lambed suture, OM suture and parietomastoid suture (more posterior)- Nasion: junction of frontal and nasal bone sutures
