Number of Carpal bones in each hand?
What is 8?
the process of bone formation, where new bone tissue is produced and deposited in the body
What is Ossification?
Forms forehead, superior part of orbits. Contains frontal sinus
What is the Frontal Bone?
Largest, strongest and only moveable facial bone. U-shaped/horseshoe shaped.
What is the Mandible?
Number of bones in the human skull?
What is 22 bones?
Number of bones in the human hand
What is 27?
are fibrous joints between skull bones. They allow the bones to be somewhat flexible, and importantly, enable the skull to expand as the brain grows.
What are Sutures?
Forms sides & roof of cranial vault.
What is Parietal?
Pyramidal shaped bones forming the upper jaw.
What is the Maxillae?
Small, flat, roughly rectangular paired bones at the bridge of the nose. Each has two surfaces (external, internal) and four borders.
What are nasal bones?
Largest of all carpal bones, centrally placed in the distal row. Articulates with the third metacarpal and sits directly distal to the lunate.
What is the Capitate?
(“soft spots”) are spaces where multiple sutures intersect, where the bones haven’t yet met/fused. At birth, several fontanelles are present; they close/ossify over time
What are Fontanelles?
On the lower lateral sides of skull and base. Associated with Hearing & balance: middle & inner ear
What is the Temporal Bone?
Known as cheekbones. Each has three main processes: temporal, frontal, maxillary (these name indicate what bone they articulate with).These are paired bones.
What are Zygomatic bones?
Very small, paired fragile bones located in the medial wall of each orbit. Have lacrimal grooves/fossae. Two surfaces (orbital, nasal) and multiple borders.
What are Lacrimal Bones?
Ulnar side of the distal row. Notable for its hook (hamulus) — a projection that can fracture, especially in sports activities (like a golf swing or hockey shot).
What is the Hamate?
is the part of the skull that encloses and protects the brain, forming the braincase.
What is the Neurocranium
Forms posterior portion and base of skull. The foramen magnum (large hole for spinal cord) is central.
What is the Occipital Bone?
Located between the orbits, forming part of anterior cranial fossa, roof of nasal cavity, medial walls of orbit, superior portion of nasal septum
What is the Ethmoid Bone?
L-shaped paired bones “tucked” between the maxillae and the pterygoid process of sphenoid
What are Palatine Bones?
Next to the trapezium in the distal row.Articulates with the second metacarpal (index finger side).
What is the Trapezoid?
is the facial skeleton that gives shape to the face and supports its features like the orbits, nasal cavity, and oral cavity.
What is the Viscerocranium?
A central, complex bone at base of skull. Shaped somewhat like a butterfly. Main parts: body, lesser wings, greater wings, pterygoid processes.
What is the Sphenoid Bone?
Thin, flat, trapezoidal bone located in the midline inside the nasal cavity. Forms inferior part of the nasal septum. Superior septum components include perpendicular plate of ethmoid.
What is the Vomer?
Curled (scroll-like) thin bones inside the nasal cavity lateral walls. They are separate bones (not part of ethmoid, which holds the superior and middle conchae).
What is the Inferior Nasal Conchae?
