Study Notes
Human Body Overview
- Comprised of two main regions: axial (torso) and appendicular (limbs).
- Axial region includes head, neck, thorax, abdomen, pelvis, and perineum.
- Appendicular region includes upper and lower limbs.
Axial Region
- Head: Top part of the body with neurocranium (skull) and viscerocranium (face).
- Neck: Connects head to thorax, starts from the first cervical vertebra.
- Thorax: Extends from the first thoracic vertebra down to the sternum, contains lungs and heart within pleural cavities and mediastinum.
Appendicular Region
- Upper Limb: Includes shoulder, arm, forearm, elbow, wrist, and hand; important bone is the humerus.
- Lower Limb: Comprises thigh, leg, and foot.
Skull and Facial Structure
- Skull: Composed of cranial bones and facial bones, supports the brain.
- Viscerocranium: Includes eye sockets, nasal cavity, zygoma, maxilla, and mandible.
- Buccal Cavity: First part of the digestive system.
Connective Tissue
- Loose Connective Tissue (Areolar Tissue): Binds organs and structures, serves as packing material.
- Periosteum: Membrane covering bones, contains blood vessels and cells for growth and repair.
Muscles and Functional Systems
- Upper Limb Muscles:
- Rotator Cuff Muscles: Includes deltoid, supraspinatus, infraspinatus, teres minor, subscapularis.
- Flexor Muscles: Biceps brachii, flexor carpi ulnaris, flexor digitorum superficialis, etc.
- Extensor Muscles: Extensor carpi ulnaris, extensor digitorum.
Lower Limb Structure
- Thigh Muscles: Comprised of quadriceps (extension) and hamstring muscles (flexion).
- Leg Structure: Contains tibia (shin bone) and fibula; divided into anterior, posterior, and lateral compartments.
Body Cavities
- Dorsal Body Cavity: Houses brain and spinal cord.
- Ventral Body Cavity: Contains organs within the thoracic and abdominal regions.
Abdomen-Pelvic Region
- No membrane separating abdominal and pelvic cavities, crucial for organ protection.
- Divided into nine regions and four quadrants for clinical purposes.
Foot Anatomy
- Composed of 22 bones: 7 tarsals, 5 metatarsals, and 10 phalanges.
- Important for stability and movement, with arches allowing for mobility.
Additional Notes
- Pes Planus: Flat foot condition characterized by flattened arches.
- Connective Tissues: Facilitate support and organization of the body’s structures, include periosteum which is vital for bone health.
