Terms, body planes Flashcards
Describe the anatomical position.
Standing upright, facing forward, feet facing forward and parallel, palms facing forward, thumbs out at 90* angle.
Describe the anatomical planes.
Transverse plane is a horizontal line that splits body into “superior” and “inferior” halves.
Sagittal plane is a vertical line that splits body into left and right halves.
Coronal plane is a vertical line that splits body into front (anterior) and back (posterior) halves.
All planes are at 90* to eachother.
Describe the terms of position - Anterior and posterior
Anterior (ventral) and posterior (dorsal).
E.g. the heart is posterior to the sternum / the triceps brachii muscle is anterior to the biceps brachii.
Describe the terms of position - Proximal and distal.
Proximal and distal are terms of position used for structures that are considered to have a beginning and an end. Proximal = closer to the origin or trunk, distal = further from the origin or trunk.
Describe the terms of position - Superior or inferior.
Superior (cranial) and inferior (causal):
Superior = closer to the head, inferior = closer to the feet.
E.g. the stomach is inferior to the heart.
Describe the terms of position - Medial and lateral.
Medial and Lateral:
Medial = towards the midline, lateral = away from the midline.
E.g. the nose is medial to the ears.
Name and describe the positional terms of laterality.
Unilateral = one side of the body
Bilateral = two sides of the body
Ipsilateral = on the same side of the body.
Contralateral = on opposite sides of the body.
Describe the positional term; parietal.
Relating to body cavity wall (pariet = cavity wall)
Describe the positional term; visceral.
Relating to organs within body cavities.
Describe the positional term; prone.
Subject is lying on stomach.
Describe the positional term;
supine.
Supine (recumbant) is when subject is lying on back.
Describe the positional term;
trunk.
Refers to the body minus the 4 limbs.
Describe the positional term;
median.
Midline of body structure.
Describe the positional term;
superficial.
Nearer the surface of the body.
Describe the positional term;
deep.
Further from surface of body.
State which cavity’s reside in the ventral cavity.
Thoracic cavity (heart, lungs)
Abdominal cavity (spleen, intestines, kidneys, liver)
Abdominal pelvic
Pelvic.
State which cavity’s reside in the dorsal cavity.
Cranial cavity
Spinal cavity
Name the seven body regions (that would be used when learning anatomy regionally).
Head & neck
Thorax
Abdomen
Pelvic & perineum
Upper limb
Lower limb
Back
Explain the terms of movement; flexion and extension.
Flexion means to bend forwards or anteriorly, reducing the anterior angle, causing flexion.
Extension refers to bending backwards and increasing the anterior angle, creating the extension.
Explain the terms of movement; abduction and adduction.
Abduction refers to the movement away from the midline.
Adduction refers to movement towards the midline of the body.
Explain the terms of movement; Medial and lateral rotation.
Medial rotation means to rotate internally, towards the midline.
Lateral rotation means to rotate externally away from the midline.
Explain the term of movement; “Circumduction”
This is a combination of movement, combining; flexion, extension, abduction and adduction.
Explain the terms of movement; Pronation and supination.
Refers to only the forearm.
Supination is when the radius and ulna are parallel to each other.
Pronation is when the radius rotates over the ulna.
Explain the terms of movement; dorsiflexion and plantarflexion.
Refers to movements at the ankle.
Dorsum is the superior surface of the foot.
Plantar is the sole of the foot.
Dorsiflexion is the backwards bending motion of the dorsum of the foot, with the foot pointing into the air.
Plantarflexion is the flexion of the ankle/foot so that the plantar surface of the foot points inferiorly.
