Introduction to anatomy Flashcards
cytology
Is the study of body cells in their internal structure?
Histology
Is a study of tissues
Systemic anatomy
Studies the anatomy of each body system
Regional Anatomy🫀🫁🧠
Examines the structure in a body region
Surface anatomy
Is the study of external anatomical features without dissection
Comparative anatomy
Examines, anatomical, similarities, and differences in different species
Embryology
Studies, developmental changes from conception to birth
Pathological Anatomy🫀🫁🧠
Examines microscopic, microscopic, anatomical changes
Graphic Anatomy🫀🫁🧠
Investigates internal structures visualized by scanning proper procedures
System, Anatomy🫀🫁🧠:
Systemic anatomy is the study of the body’s organ systems that work together to carry out complex functions.
The integumentary system
The skeletal system
The articular system
The muscular system
The nervous system
The circulatory system
The cardiovascular system
The lymphatic system
The alimentary or digestive system
The respiratory system
The urinary system
The genital (reproductive) system
The endocrine system
Regional Anatomy🫀🫁🧠
Regional anatomy (topographical anatomy) considers the organization of the human body as major parts or segments.
Head
Neck
Trunk
back
thorax
abdomen
pelvis/perineum
paired upper limbs and lower limbs.
All the major parts may be further subdivided into areas and regions.
Regions of the head
- Frontal region, parietal, occipital, temporal, Auricular, 6. mastoid
Facial region:
7. Orbital, Infra-orbital, buccal, Parotid, zygomatic, Nasal, Oral region, 14. Mental region
Surface Anatomy
Structures are perceptible to touch (Palpable) in the living body at rest and in action
Physical examination:
- Palpation
- ophthalmoscope
- Stethoscope
Clinical anatomy
The … nerve provides innervation to this area of muscle,” clinical anatomy asks, “paralysis of some or all facial muscles on the affected side indicates a lesion of which nerve?”
Anatomical cavity (important) slide 10
Dorsal cavity and ventral cavity
Dorsal cavity
Completely encased in bone subdivided into cranial cavity and vertebral cavity
Cranial cavity (endocardium)
Is formed by bones of the cranium. Houses the brain
vertebral canal
Is formed by the bones of the vertebral column. Houses the spinal cord.
Ventral cavity
Interiorly placed in the body portioned into:
- Superior thoracic cavity
- Inferior abdominopelvic pelvic cavity
Anatomicomedical Terminology
Anatomical position
Anatomical planes and sections
Terms of relationship and comparison
Terms of laterality
Terms of movement
Anatomical variation
Anatomical position
The anatomical position is the standard reference position of the body used to describe the location of structures
Characteristics of anatomic position:
- head, eyes (gaze), and toes directed anteriorly
- upper limbs by the sides with the palm facing interiorly
- lower limbs close together with the feet parallel in the toes directly
Anatomical planes
Anatomical descriptions are based on the four imaginary planes that intersect the body in the anatomical position
Medium plain
Median sagittal plane, the vertical anterior posterior plane, devise a body into right and left halves
Sagittal planes
Vertical planes passing to the body parallel to the median plane
Anatomical sections
The main use of anatomic plants to describe sections
Frontal (coronal) planes
Are vertical planes dividing the body into anterior (front) and posterior (back) parts
Transverse planes
Are horizontal planes dividing the body into superior (upper) and inferior (lower) parts
Note: radiologist referred to transverse plan as transaxial, which is commonly shortened to axial planes
Longitudinal sections
Run length ways or parallel to the long axis of the body
Note: median, sagittal, and frontal plants are the standard longitudinal sections
Transverse section (cross section)
Our slices of the body, or its parts that are cut at right angles to the longitude of axis of the body, or of any of its parts
Oblique sections
Are slices of the body or any of its parts that are not cut along the previously listed anatomical planes
