Testlet 1 Flashcards
(24 cards)
signs of inflammation
- internal bleeding
- redness
- heat
- swelling
- pain
- loss of function
leukocytes
wandering cells
macrophages
resident cells
mast cells
resident cells
badly bruised right upper lip
- stratified squamous, non-keratinized epithelium
- non-keratinized = waterproof
possible fracture of right zygomatic bone
- primary woven bone shows up first
- periosteum helps with bone repair (2 layers)
- osteoblasts: differing bone making cells; active in protein synthesis, promotes calcification by alkaline phosphatase
- osteocyte: secrete growth factors which stimulate osteoblast or osteoclasts
- osteoclasts: break down damaged bone for new bone to come in
black eye
damage to eye: choroid is vascular and broken blood vessels may arise
vascular layer of eye: choroid, ciliary body, lens, iris
drooling from corner of mouth
- may signal numbness or damage to CN 9 (glossopharyngeal)
- submandibular gland?
- cilia moves mucus
able to smile only on non-affects side
- facial expression innervated by facial nerve 7
- contralateral (opposite) expression
right eye was adducted
oculomotor (CN3) medial rectus: muscle in eye that does adduction action
-Cranial nerve 6
pupil dilated
- sympathetic response
- dilator pupillae muscle
unable to tear in affected eye
- CN 7 (facial): lacrimal gland innervation
- parasympathetic innervation
tenderness, swelling, deformity of right upper limb
- tenderness can be felt due to ascending spinothalamic tract to feel pain
- swelling due to inflammation; leukocytes again come in
abnormal movements of right upper limb
- possible UMN injury (spinal cord injury); spastic paralysis of the upper limb
- precentral gyrus concerned with force of muscle contraction + speed and direction and direction of movements
unable to extend digits or wrist (wrist drop)
- defect in corticospinal tract
loss of pain and tactile sensation on the lateral portion of the dorsum of the hand
- sensory: ascending tract in the proprioception is affected in the dorsal column
- ascending tract for pain is spinothalamic tract
- pain is pinpointed when it travels to thalamus to the postcentral gyrus
displaced fracture
- perichondral proliferation
- osteoclasts: break down old or damaged bone to allow for new bone formation
deltoid muscle
-reticular tissue is in the hemopoietic portion of bone marrow and can bind smooth muscle cells together.
distal fragment of humerus displaced proximally
Periosteum:
Two Dense Layers
- Outer Layer: fibrous, vascularized, innervated
- Inner Layer: source of osteoprogenitor cells and contributes to bone formation
Endosteium:
- single layer of osteoprogenitor cells and osteoblasts
the position of his right eye suggested injury most likely to a muscle innervated by which cranial nerve
CN 6
the muscles responsible for preventing drooling and producing a smile are innervated by which cranial nerve
CN 7
the displacement of the distal bone fragment involves contraction of which of the following muscles?
coracobrachialis
the displacement of the proximal bone fragment involves contraction of which of the following muscles
deltoid
the movement affected on the patients right hand suggests injury to the
radial n
