ANAT 150 Lab Practical 2: Skeletal System Review

Comprehensive practice flashcards covering the axial and appendicular skeletons, compact bone anatomy, and specific landmarks of the adult and fetal skull based on Exercises 9 and 10.

The skeletal system is divided into two primary sections: the axial skeleton and the __________ skeleton.

Appendicular

The axial skeleton includes the skull, mandible, hyoid bone, vertebral column, sternum, rib cage, sacrum, and __________.

Coccyx

The pectoral girdle and upper extremity include the clavicle, scapula, humerus, radius, and __________.

Ulnar

In the upper extremity, there are __________ carpal bones, __________ metacarpal bones, and __________ phalangeal bones.

$8$, $5$, $14$

The pelvic girdle and lower extremity consist of the pelvic bone, femur, tibia, fibula, patella, and __________ tarsal bones.

$$7$$

The lower extremity contains __________ metatarsal bones and __________ phalangeal bones.

$5$, $14$

The microscopic structures of compact bone include the central canal, lacuna, osteocyte, canaliculus, and three types of __________.

Lamella

Compact bone contains three specific types of lamella: concentric, interstitial, and __________.

Circumferential

While most skull bones are single, there are two __________ bones and two __________ bones in the adult skull.

Parietal, Temporal

The __________ bone contains features such as the superior nuchal line, inferior nuchal line, and the occipital condyle.

Occipital

The __________ bone includes the external auditory canal, mastoid process, styloid process, mandibular fossa, and petrous portion.

Temporal

The __________ bone is characterized by the greater wing, lesser wing, and the sella turcica.

Sphenoid

The __________ bone consists of the crista galli and the cribriform plate.

Ethmoid

The zygomatic arch is formed by the zygomatic process of the temporal bone and the __________ process of the zygomatic bone.

Temporal

Skull canals involve the optic, carotid, hypoglossal, and both the external and internal __________ canals.

Auditory

Major foramina of the skull include the foramen rotundum, foramen ovale, foramen spinosum, jugular foramen, and the __________.

Foramen magnum

The two types of fissures found in the eye orbit are the __________ orbital fissure and the __________ orbital fissure.

Superior, Inferior

The two paranasal sinuses identified in Exercise 10 are the __________ sinus and the __________ sinus.

Frontal, Sphenoidal

The nasal septum is composed of the vomer bone, nasal cartilage, and the __________ plate of the ethmoid bone.

Perpendicular

There are three nasal conchae: the superior, middle, and __________ nasal concha.

Inferior

The hard palate is formed by the horizontal plate of the palatine bone and the __________ process of the maxillary bone.

Palatine

The __________ process of the maxillary bone holds the teeth.

Alveolar

The four main sutures of the skull are the coronal, sagittal, lambdoid, and __________ sutures.

Squamous

In the fetal skull, the four fontanels are the frontal, occipital, sphenoidal, and __________ fontanels.

Mastoid

The mandible contains several landmarks: the body, angle, ramus, mandibular notch, and the __________.

Mandibular foramen
