Anatomical Terms Flashcards
Divides the body into left and right
Midsagittal or sagittal
3 major planes
Midsagittal
Transverse
Coronal
Divides into superior and inferior
Transverse
Horizontal plane
Transverse plane
Divides into ant and post
Coronal plane
Frontal plane

2 body cavities:
Dorsal cavity
Ventral cavity
Dorsal cavity is divided into
Cranial
Spinal
Structure that separates cranial and spinal cavity
Foramen magnum
Ventral cavity is divided into
Thoracic
Abdominipelvic
Structure that separates thoracic and abdominopelvic cavity
Diaphragm
2 subdivisions of abdominopelvic cavity
Abdominal cavity
Pelvic cavity
Not enclosed by bones
Abdominal cavity
Cavity or divisions in the head and neck region
Cranial cavity
C1-C7
Body being divided into
Planes
Towards the head
Superior
Cranial
cephalic
Away from the head
Tail bone- coccyx
Inferior
Caudal
Belly
Ventral

Towards the median
Medial
Membrane lining the cavity walls
Parietal
Ex of parietal
Periosteum
Cpventral body cavity that houses a grp of internal organs
Visceral
Ex of visceral

2 major approaches
Systemic
Regional anatomy
Common functions among organs
Identify func and structures that particularly perform common function
Systemic
Approach: specific part of the body
Regional anatomy
Approaches in examining internal structures
Surface anatomy
Anatomical imaging
External features such as bony projections
Surface anatomy
Involves using xrays, mri ultrasound
Anatomical imaging
Examines shape and markings on the surface of the body
Surface anatomy
Impt of surface anatomy
- Help diagnose medical conditons and treat patients
- essential in locating and identifying anatomic structures
4 techniques insurface anatomy
Visual inspection
Palpation
Percussion
Auscultation
Directly observe the structure and markings of surface featured
Visual inspection
Feeling with firm pressure or perceiving by the sense of touch
Palpation
Precisely locate and identify anatomic features under the skin
Palpation
Tap sharply on specific body sites to detect resonating vibrations
Percussion
Listen to sounds omitted from organs
Auscultation
Muscles attach to superior nuchal
Trapezius
Sternocleidomastoid
Relatively small area
Large number of impt struc are compressed
Head and neck region
Protective structures/nerve structures
Brain
Sense organs
Cranial nerves
Branches of cervical plexus
