Example Question #388 : Gross Anatomy
What suture runs laterally from the top of the cranium and ties together the frontal and two parietal bones?
Sagittal suture
Squamosal suture
Coronal suture
Basilar suture
Lambdoidal suture
Coronal suture
The coronal (frontal) suture runs laterally from the top of the cranium and ties together the frontal and two parietal bones.
The sagittal suture runs along the top of the cranium, between the two parietal bones. The lambdoidal suture ties together the occipital and two parietal bones on the posterior cranium. The squamosal suture is the area where the squamosal section of the temporal bone is beveled and overlaps the parietal bone. The basilar suture, also referred to as spheno-occipital synchondrosis, is a suture between the occipital and sphenoid bones.
Example Question #381 : Gross Anatomy
What suture runs between the temporal bone and the parietal bone?
Squamosal suture
Sagittal suture
Basilar suture
Coronal suture
Lambdoidal suture
Squamosal suture
The squamosal suture is the area where the squamosal section of the temporal bone is beveled and overlaps the parietal bone.
The sagittal suture runs along the top of the cranium, between the two parietal bones. The coronal suture runs laterally from the top of the cranium and ties together the frontal and two parietal bones. The lambdoidal suture ties together the occipital and two parietal bones on the posterior cranium. The basilar suture, also referred to as spheno-occipital synchondrosis, is a suture between the occipital and sphenoid bones.
Example Question #381 : Gross Anatomy
What suture runs between the two parietal bones, running antero-posteriorally along the top of the cranium?
Squamosal suture
Coronal suture
Basilar suture
Sagittal suture
Lambdoidal suture
Sagittal suture
The sagittal suture is the long suture that runs between the two parietal bones, running antero-posteriorally along the top of the cranium.
The coronal suture runs laterally from the top of the cranium and ties together the frontal and two parietal bones. The lambdoidal suture ties together the occipital and two parietal bones on the posterior cranium. The squamosal suture is the area where the squamosal section of the temporal bone is beveled and overlaps the parietal bone. The basilar suture, also referred to as spheno-occipital synchondrosis, is a suture between the occipital and sphenoid bones.
Example Question #51 : Identifying Bones Of The Skull
Which nerve passes through the optic canal?
Cranial nerve IV
Cranial nerve II
Opthalmic branch of cranial nerve V
Cranial nerve III
Cranial nerve X
Cranial nerve II
The optic canal is also referred to as the optic foramen. It is a short canal through the lesser wing of the sphenoid bone. The optic canal transmits the optic nerve (cranial nerve II) and the ophthalmic artery into the orbital cavity.
Example Question #52 : Identifying Bones Of The Skull
A portion of the trigeminal nerve emerges from which foramen?
Foramen magnum
Foramen ovale
Obturator foramen
Jugular foramen
Cribriform plate
Foramen ovale
The three branches of the trigeminal nerve, the ophthalmic, maxillary, and mandibular branches leave the skull through three separate foramina. The opthalmic branch exits through the superior orbital fissure, the maxillary branch exists through the foramen rotundum, and the mandibular branch exits through the foramen ovale.
The spinal cord, accessory nerve, and various arteries pass through the foramen magnum. The cribriform plate allows the emergence of the olfactory nerve. The obturator foramen is in the hip.
Example Question #53 : Identifying Bones Of The Skull
Where is the lambdoid suture located?
Between the parietal bones and the temporal bones
Between the temporal bones and the parietal bones
Between the parietal bones and the occipital bone
Between parietal bones
Between the frontal bone and the parietal bones
Between the parietal bones and the occipital bone
Humans skulls contain sutures, which are dense fibrous connective tissue joints that holds the bony plates of the skull together. The lambdoid suture connects the parietal bones with the occipital bone. This suture is actually continuous with the occipitomastoid suture.
Example Question #184 : Bones
Which bones are a part of the axial skeleton?
Bones of the head
Bones of the arms
Bones of the legs
Bones of the fingers
Bones of the head
The skeletal system is divided into the axial skeleton and the appendicular skeleton. The axial skeleton consists of bones of the head, ribs, vertebral column, and sternum. In contrast, the appendicular skeleton consists of bones of the extremities, including the fingers, arms, and legs.
Example Question #394 : Gross Anatomy
Which structure separates the parietal bones from the occipital bone?
None of these
Coronal suture
Lambdoid suture
Inferior nuchal line
Sagittal suture
Lambdoid suture
The lambdoid suture is located between the parietal bones and the occipital bone. When looked at with the sagittal suture from a posterior view, it creates a lambda shape.
Example Question #62 : Identifying Bones Of The Skull
Which of the following is not a part of the ethmoid bone?
Perpendicular plate
Crista galli
Middle nasal concha
Pterygoid processes
Cribriform plate
Pterygoid processes
The pterygoid processes are inferior projections from the greater wings of the sphenoid bone. They attach to muscles that help with mastication.
Example Question #63 : Identifying Bones Of The Skull
Which cranial bone forms the posterior base of the skull?
Occipital
Parietal
Frontal
Temporal
Mandible
Occipital
The occipital bone is located at the posterior aspect of the head, inferior to the parietal bones. It contains a large opening called the foramen magnum which allows connection of the brain and spinal cord.
