Anatomy Flashcards
Where does the trochlear articulate?
With the head of the ulna
Where does the head of the capitulum articulate?
With the head of radius
What movements are possible at the sternoclavicular joint?
All movements
What movements are possible at the acromioclavicular joint?
It’s a planar joint and therefore allows back and forth, side-to-side movements
What movements are possible at the humeroulnar and humeroradial joint?
Hinge joint –> flexion and extension
What movements are possible at the talocrural joint?
Hinge joint –> dorsiflexion and plantarflexion
What movements does the anterior thigh facilitate?
Hip flexion and knee extension
What movements does the posterior thigh facilitate?
Hip extension and knee flexion
Which foramina are in the middle cranial fossa?
Superior orbital fissure, foramen rotundum, foramen ovale and carotid canals
Which foramina are in the posterior cranial fossa?
Foramen magnum, internal auditory meatus and jugular foramen
Describe the 4 muscle of the abdomen
Internal oblique (into back pockets), external oblique (into front pockets), tranverse abdominis, rectus abdominis
What is abdominal membrane inflammation known as?
Ascites
Where is the thymus gland located?
In line of sternum
Where are the thyroid and parathyroid glands located?
In brainstem region
Where are the pineal and pituitary glands locate?
Central cerebrum
Where does the descending aorta run in relation to the spine?
From T4-T12, left and anterior to the spine
At which spinal level does the abdominal aorta bifurcate into the common iliac arteries?
L4
Which structures pass through the diaphragm, and at what spinal level
Aorta - T12
Oesophagus - T10
Vena cava - T8
Where does the blood from branches of the abdominal aorta drain to?
Hepatic portal vein
Which nerve carries 90% of parasympathetic nervous fibres?
Vagus (CN X)
How do the parasympathetic and sympathetic nervous systems change the heart rate?
Parasympathetic - releases ACh at SAN and AVN –> reduces HR
Sympathetic - releases noradrenaline at SAN and AVN –> increases HR
Where does the thoracic duct join the venous system?
At anastomoses of the left internal jugular and subclavian veins
Where does lymph from the upper left quadrant of the body drain?
Thoracic duct
Where does lymph fromt the upper right quadrant of the body drain?
Right lymphatic trunk
What is the most common type of chest X-ray?
PA (posterior-anterior) where lungs are larger and heart isn’t as magnified
