Study Notes
Introduction to Anatomy
- Course title: Introduction to Anatomy
- Prepared by: Prof. Amjad Al-Shatarat and Dr.Ala'a Yousef
- Department: Department of Biomedical Sciences
- Faculty: Faculty of Medicine
- University: Aqaba Medical Sciences University
- Year: 2024
The Axial Skeleton
- Skull: Supports and balances the head and provides protection
- Vertebral Column: Supports the body and protects the spinal cord
- Thorax: Protects the organs within the chest cavity
Appendicular Skeleton
- Shoulder Girdle: Supports the arm
- The Arm: Provides movement
- Hand: Facilitates fine motor skills
- Pelvic Girdle: Supports the leg
- The Leg: Provides support and movement
- Foot: Enables locomotion
Bones of the Axial Skeleton
- Skull: Parts include cranial and facial portions, and many immobile bones. The mandible is the only moveable bone.
- Pectoral (Shoulder) Girdle: Made up of the clavicle and scapula
- Thorax: Sternum and ribs
- Vertebral Column: Forms the spine
- Pelvic Girdle: Forms the pelvis
The Skull (Detailed)
- Mobility: The mandible is the only mobile bone in the skull, allowing for movement in the temporomandibular joint
- Division: Bones can be divided into Cranium (brain case) and facial bones
- Cranium: Provides protection and enclosure of the brain.
- Vault: The upper part of the cranium, providing protection for the brain
- Base: The lowest section of the cranium
- Sutures: Immobile joints that hold the skull bones together
Skull- Superior View
- Bones: Frontal, Occipital, and two Parietal bones joined by sutures
- Sutures: Are immoveable joints where the bones are joined.
The Skull- (cont.)
- Temporalmandibular joint (TMJ) The only movable joint of the skull connected by the mandible which functions in chewing
- Bones of the Face: The remaining skull bones not a part of the skull
The Thorax
- Functions in protecting internal organs
- Composed of the Sternum, ribs, and vertebral column
The Thoracic Wall
- Sternum: A flat bone situated in the center of the chest.
- Ribs: 12 pairs of ribs providing protection and shape
- Vertebral Column: Supports and protects the spinal cord
The Sternum
- Parts: Manubrium, Body, and Xiphoid process
- Location: The center of the chest
- Function: Protects the vital organs
The Ribs
- Types: True, False, Floating
- Attachment: To the spine posteriorly, and in different ways to the sternum anteriorly.
The Vertebral Column
- Composition: 33 bones composed of vertebra types: Cervical, Thoracic, Lumbar
- Sacrum: The fused sacral vertebrae
- Coccyx: The fused coccygeal vertebrae
A Typical Vertebra
- Body: Anterior portion of the vertebra
- Arch: Posterior portion of the vertebra
- Foramen: Opening formed by the arch, housing the spinal cord
- Processes: Spinal, transverse, and articular processes
Curvature of The Vertebral Column
- Fetal stage: One single curve.
- After Birth: Cervical, Thoracic and lumbar curves develop sequentially, helping to support bipedal posture
- Thoracic, Lumbar: Concave posteriorly
Abnormal Curves of the Vertebral Column
- Scoliosis: Lateral curvature of the spine
- Kyphosis: Increased curvature in the thoracic region
- Lordosis: Increased curvature in the lumbar region
