Notes

Front 1

Specialized(Supportive) Connective Tissue
1) Cartilage

Back 1

cells(chondrocytes) found in lacunae which are surrounded by matrix that’s solid yet flexible(poor blood supply)

Hint 1

 1) Hyaline : lots of collagen fibers, found at ends of bones in joints to decrease friction. Also in nose, larynx, trachea, joining ribs to sternum. Embryonic skeleton composed of this
 2) Elastic : wavy elastic fibers allowing flexibility (ears)
 3) Fibrocartilage : has matrix with strong collagen fibers. Specialized to withstand tension and pressure(inter vertebral discs, wedges in knee)

Front 2

Specialized(Supportive) Connective Tissue
2) Bone

Back 2

most rigid connective tissue, osteocytes surrounded by hard matrix of inorganic salts(calcium) deposited around collagen fibers. Functions to provide support, protection, and calcium depot

Hint 2

• 2 types of bone tissue
 1) Compact – dense, hard, shiny surface; makes up shaft of bone
 2) Spongy – open lattice work, found at ends of long bones, and inside most bones
• Whole bones can also be categorized as: a) long bones(femur, humerus); b) flat bones(sternum, scapula); c) short bones(carpals, tarsals); d) irregular bones(vertebrae) or; e) sesmoid bones(patella)

Front 3

Specialized(Supportive) Connective Tissue
3) Fluid connective tissue

Back 3

3 types
1. Blood
2. Lymph
3. Muscle

Hint 3

3 types of muscle tissue
1. Skeletal : allows movement of body and body parts, accounts for 40% and 34% of body weight in men and women. Skeletal muscle under voluntary control. Large cells called muscle fibers; they are multinucleated and striated in appearance
2. Smooth : not striated in appearance, but does have overlapping myosin,a nd actin, smaller cells that are monucleated. Found in internal organs, GI tract, uterus, eyes, arteries, controlled by autonomic (involuntary) nervous system
3. Cardiac : striated in appearance, small monucleated cells joined by intercalataed disc to allow syncytical contraction. Capable of self-excitation, but rate and strength of contractions controlled by autonomic nervous system

Front 4

4 Properties of all muscle types

Back 4

• 1) excitability(electrical impulse)
• 2) extensibiltty(longer than resting length)
• 3) elasticity
• 4) contractility(generates force)

Front 5

Specialized(Supportive) Connective Tissue
4) Nervous

Back 5

specialized to allow for communication with both internal and with external environment. Consists of both neurons and neuroglia.

Front 6

1) Neurons

Back 6

: specialized to generate and receive electrical impulses(excitable). Various, but each has dendrites to receive input, soma(cell body) with nucleus, and axon to carry impulses away to neighboring excitable cells. Axon may be myelinated to increase rate of condition of impulses

Front 7

3 functions of neurons

Back 7

• 1) receive input(afferent) detects
• 2) integrate information(CNS) tells to read a response
• 3) motor output(efferent) brings about a response

Front 8

2) Neuroglia

Back 8

many glial cells than neurons, these do not generate or receive electrical impulses. Many different types including : microglia, astrocytes, oligodendrocytes. Neuroglia provide support and nutrients to neurons, protect neurons from bacteria and cellular debris, and form myelin
