Epithelial tissue - 🧠 ANSWER ✔✔Covers body, lines cavities, forms glands
→ no blood vessels, supplied by subcutaneous tissue
Connective/supportive tissue - 🧠 ANSWER ✔✔Binds to or supports
structures (tendons, ligaments, dermis, adipose, blood, bones, cartilage)
Muscle tissue - 🧠 ANSWER ✔✔Movement, charges shape of organs
(skeletal, cardiac (can't repair) smooth (can repair))
Metaplasia - 🧠 ANSWER ✔✔Epithelial cells replaced with another type of
epithelial cell, an attempt to survive chronic irritation
, Dysplasia - 🧠 ANSWER ✔✔Change in shape, size, and organization
because of chronic irritation, precursor to cancer sometimes
Autonomic Nervous System - 🧠 ANSWER ✔✔Regulate homeostasis
through CNS, PNS, and endocrine
Nerve impulse in PNS to CNSCNS impulses to stimulate organs, glands,
muscles
Sympathetic Nervous System - 🧠 ANSWER ✔✔Fight or flight
Increase HR, BP, RR, broncho + pupil dilation, glucose breakdown
Decrease elimination, digestion, reproduction
CNS in thoracic and lumbar stimulate nerve ganglia
NT released
Primary NT: norepinephrine and epinephrine
Adrenergic/Sympathetic Receptors - 🧠 ANSWER ✔✔Alpha and beta
receptors respond to epinephrine and norepinephrine -> different receptors
(A1, A2, B1, B2) have different responses
Alpha and Beta Adrenergic Agonists - 🧠 ANSWER ✔✔Treat: hypotension
(decrease BP), shock, bronchospasm, asthma
