Cochlea
What’s that nerve baby
Vestibulocochlear nerve baby
What are those!!!
These. Are. My. SEMICIRCULAR CANALS
Which is oval window and which is round window?? (Yes I think ur dumb)
Guess what! The round window is the round window and the oval window is the oval window
What’s that bulge (lol)
Vestibule
Identify axon, axon hillock, and dendrites
Dendrites on the left, axon hillock on the bottom right, axon on the middle right
Identify nucleus and nissl body
Nissl bodies are the little blue things and the nucleus is the big round one
What is this thing
A Schwann cell
What are those
Nodes of ranvier
Identify Schwann cell nucleus, myelin sheath, axon, mitochondria
Identify dorsal nerve roots, dorsal root ganglia, and the ventral nerve roots
Identify central canal, anterior median fissure, and posterior median sulcus
Identify anterior funiculus, lateral funiculus, and posterior funiculus
Identify anterior horns, posterior horns, lateral horns
Identify pia mater, arachnoid, and dura mater
Pia is inside, arachnoid is the webby one, and dura mater is the outside one
Identify posterior median sulcus, anterior median fissure, gray commissure, central canal, and meninges
Identify

Identify area of nerves and innervations
Cervical plexus (C1-C4) innervates muscles that control larynx, diaphragm, and neck. Sensory innervations to skin of neck, shoulder, and upper limb
Identify area of nerves
Brachial plexus ( C-5-8, T1), innervates skin and muscles in the shoulder and upper limb. Branches include the auxillary, musculocutaneous, radial, median, and ulnar nerves
Identify nerve and innervation (top marker)
Musculocutaneous nerve, cutaneous innervation of lateral forearm, motor innervation of biceps brachii, brachialis, and coracobrachialis
Identify nerve and innervation (bottom two)
Radial nerve, motor innervation of triceps brachii, anconeus, and extensor muscles of the forearm, cutaneous innervation to posterior arm and hand
Identify nerve and innervation (top marker)
Musculocutaneous nerve, cutaneous innervation of lateral forearm, motor innervation of biceps brachii brachialis, coracobrachialis
Identify nerve and innervation (bottom marker)
Ulnar nerve, motor innervation of flexor Carpi ulnaris, cutaneous innervation of hand
Identify nerve and innervation (second from bottom marker)
Median nerve, motor innervation of flexor muscles forearm and pronator teres, cutaneous innervation of palm and digits, pressure on this nerve causes carpal tunnel syndrome
What is this area of nerves plus what is that little box of nerves
Thoracic nerves (t2-t11) includes intercostal nerves (little box), motor innervation to intercostal muscles and muscles of the abdominal wall, sensory inner action to anterior trunk
Identify area and what is pointed out and innervations
The lumbar plexus (t12, L1-L4), femoral nerve: cutaneous and muscular branches innervate hip and quadriceps muscles. Gives rise to saphenous nerve which provides sensory innervation to medial leg
Obturator nerve: sensory and motor innervation of thigh and adductor muscles
Identify nerves
Femoral nerve, top
Obturator nerve, middle
Saphenous nerve, bottom
Identify area and nerve
Sacral plexus (L4-L5, S1-S4) innervates posterior thigh and lower limb, includes sciatic nerve which innervates hamstring muscles (posterior thigh)
Identify sciatic nerve and it’s two branches
Sciatic nerve is top, tibial nerve is right, peroneal nerve is blue on left.
Peroneal nerve is the common fibular nerve and it is sensory innervation to anterior and later aspects of the lower leg and top of the foot; motor innervation to peroneus Longus and muscles responsible for plantar flexion, nerve damage results in foot drop.
Tibial nerve travels to posterior leg, motor innervation to plantar flexors of the leg; sensory innervation to posterior leg and sole of foot
Identify cranium, dura mater, arachnoid, subarachnoid space, and pia mater
Identify cerebral hemispheres, the sulci, the convolutions or gyri (bumps), and the cerebellum
Identify frontal lobe, parietal lobes, occipital lobes, temporal lobe
Identify midbrain, pons, medulla oblongata, cerebellum, corpus callosum
Identify thalamus, diencephalon, hypothalamus
Identify pons, midbrain cerebellum, medulla oblongata, diencephalon, corpus callosum
Identify pituitary gland, thalamus, and hypothalamus
