| Congenital anomalies are present at birth, while acquired anomalies develop later due to factors like injury or disease. | | | | 16 | What is the term for the abnormal development of the skull? | Craniosynostosis is a condition where one or more cranial sutures fuse prematurely, affecting skull shape. | | | | 17 | What is the role of environmental factors in skeletal anomalies? | Environmental factors, such as nutrition and exposure to toxins, can influence the development of skeletal anomalies. | | | | 18 | What is the significance of the tibial tuberosity? | The tibial tuberosity is an important landmark for muscle attachment and can indicate growth patterns. | | | | 19 | Give an example of a common skeletal anomaly. | Spina bifida is a common congenital skeletal anomaly where the spine does not close completely. | | | | 20 | What is the term for the abnormal development of the spine? | Spondylolisthesis is a condition where a vertebra slips out of place, affecting spinal alignment. | | | | 21 | What is the role of the patella in the knee joint? | The patella protects the knee joint and improves the leverage of the quadriceps muscle. | | | | 22 | What is the term for the abnormal growth of bone? | Osteopetrosis is a condition characterized by excessive growth and density of bone, leading to fragility. | | | | 23 | What is the significance of the vertebral foramen? | The vertebral foramen houses the spinal cord and is crucial for protecting neural structures. | | | | 24 | What is osteogenesis imperfecta? | Osteogenesis imperfecta is a genetic disorder characterized by fragile bones that break easily. | | | | 25 | What is a non-metric trait in skeletal anatomy? | Non-metric traits are qualitative variations in skeletal features that do not follow a standard measurement. | | | | 26 | What is the term for the abnormal development of the pelvis? | Pelvic dysplasia refers to abnormal development or formation of the pelvic bones. | | | | 27 | What are accessory bones? | Accessory bones are extra bones that can form in various locations, such as the foot or wrist. | | | | 28 | What is the significance of the os acromiale? | Os acromiale is an accessory bone at the acromion of the scapula, which can affect shoulder function. | | | | 29 | What is the term for the abnormal development of the wrist? | Wrist dysplasia refers to congenital anomalies affecting the structure and function of the wrist bones. | | | | 30 | What is the role of the appendicular skeleton? | The appendicular skeleton facilitates movement and includes the limbs and girdles. | | | | 31 | What is polydactyly? | Polydactyly is a condition where an individual has extra fingers or toes. | | | | 32 | What is a common feature of achondroplasia? | Achondroplasia is characterized by short stature and disproportionately short limbs due to abnormal cartilage formation. | | | | 33 | What are the common types of skeletal dysplasias? | Common types include achondroplasia, thanatophoric dysplasia, and osteogenesis imperfecta. | | | | 34 | What is the term for the fusion of cervical vertebrae? | Cervical vertebrae fusion is known as cervical vertebral fusion or block vertebrae. | | | | 35 | What is the role of imaging in diagnosing skeletal anomalies? | Imaging techniques like X-rays, CT scans, and MRIs help visualize and diagnose skeletal anomalies. | | | | 36 | What is the term for the abnormal growth of cartilage? | Chondrodysplasia refers to a group of disorders characterized by abnormal cartilage growth. | | | | 37 | What is the significance of the zygomatic arch in skeletal analysis? | The zygomatic arch is used in anthropology to assess facial structure and can indicate dietary adaptations. | | | | 38 | What is the role of the sacrum in the skeletal system? | The sacrum connects the spine to the pelvis and supports the weight of the upper body. | | | | 39 | What is the clinical significance of the iliac crest? | The iliac crest is often used as a site for bone grafting and is important in assessing pelvic morphology. | | | | 40 | What is a cleft palate? | A cleft palate is a congenital anomaly where there is an opening in the roof of the mouth due to incomplete fusion. | | | | 41 | What is the role of the axial skeleton? | The axial skeleton supports the head, neck, and trunk, and protects the brain and spinal cord. | | | | 42 | What is the significance of the greater sciatic notch? | The greater sciatic notch is important for the passage of nerves and blood vessels from the pelvis to the lower limb. | | | | 43 | What is the term for the abnormal curvature of the spine in the lateral plane? | Scoliosis refers to an abnormal lateral curvature of the spine. | | | | 44 | What is the significance of the calcaneus in the foot? | The calcaneus is the largest bone in the foot and plays a key role in weight-bearing and movement. | | | | 45 | What are skeletal anomalies? | Skeletal anomalies are variations in the normal structure of bones that can be congenital or acquired. | | | | 46 | What is scoliosis? | Scoliosis is a lateral curvature of the spine that can be idiopathic or due to other conditions. | | | | 47 | What is the term for the abnormal development of the foot? | Clubfoot, or talipes, is a congenital deformity where the foot is twisted out of shape or position. | | | | 48 | What is a common non-metric trait found in human skulls? | The presence of a sagittal crest is a non-metric trait that indicates muscle attachment for strong jaw muscles. | | | | 49 | What is the significance of the humeral head in shoulder anatomy? | The humeral head articulates with the glenoid cavity of the scapula, forming the shoulder joint. | | | --- Study this deck interactively with FSRS-6 spaced repetition, audio review, and multiple-choice mode at [Flashcards World](https://flashcards.world/flashcards/sets/8802cf63-a4f0-41d1-80cb-befb2fd60f16/).
