Q

Nervous tissue

A

Nerves, the spinal cord, and the brain; works to receive, interpret, and respond to signals. ( has a bunch of purple dots all around the picture and also has this oddly weird circular and abnormal shape that is purple and connects to all the dots)

Q

muscle tissue

A

looks like a bunch of purple quinoa grains with white in between the purple. Striated muscle tissue, also known as skeletal muscle tissue, is attached to bones. Smooth muscle tissue is in the walls of internal organs. Cardiac muscle tissue is in the walls of the heart, where it provides the ability to contract.

(skeletal, connective, adipose)

Q

connective tissue

A

( IT IS THE ALL RED PICTURE) supports and connects other tissue types in the body. It is attached to and in between other tissue types in the body. Adipose tissue (fat) is a type of connective tissue.

surrounding the eye socket , about an in thick all around

39
Q

orbicularis oris muscle

A

surrounding the mouth , about an in thick all around

40
Q

temporalis muscle

A

left and right temporalis looks like a shark tooth that was plastered where your ear is and is elongated to the occipital and the front cap

41
Q

skeletal system

A

organ system composed of bones and cartilage

42
Q

compact bone

A

dense osseous tissue that can withstand compressive forces ( its inside the bone ;the larger surface is covered)

43
Q

spongy bone aka cancellous bone

A

the circular things in the bones; trabeculated osseous tissue that support …

44
Q

long bone

A

cyilindar shaped bone that is longer that it is wide ; can be found in the femur

45
Q

short bone

A

cubed shaped bone that is approx equal in length,width etc ( carpals, toes)

46
Q

sesamoid bone ( also part of the short bone)

A

small round bone embedded in a tendon ( patellar)

47
Q

flat bones

A

thin and curved bone ; swerves as a point of attachment ( the sternum)

48
Q

irregular bone

A

bone of complex shape; thoracic vertebra

49
Q

Diaphysis

A

tubular shaft that runs between proximal and distal the longest part ( A)

50
Q

periosteum

A

fibered membrane covering the outer surface of bone; the bottom long part but not the bottom bottom

51
Q

perforating fibers aka sharpeys fibers

A

a matrix of connective tissue consisting of bundles of strong cancellous fibers ( that weird flap with spikes)

52
Q

Epiphyses

A

wide section at the end of the long bone and start

53
Q

articular cartilage

A

the thin line surround the bone

54

61
Q

central canals

A

contains blood vesels (aka haversian canal;)

62
Q

osteocyte

A

a bone cell, formed when an osteoblast becomes embedded in the matrix it has secreted.

63
Q

Muscle Contraction: Action Potential on T-Tubule

A

After acetylcholine attaches to its receptors on the sarcolemma, the muscle fibers become more positively charged.

This generates an action potential that travels along the sarcolemma and into the transverse (T) tubules.

64
Q

Muscle Contraction: Calcium Release

A

As the action potential travels along the T-tubules, calcium is released from the sarcoplasmic reticulum.

65
Q

Muscle Contraction: Troponin Binding

A

Calcium binds to troponin on the actin filaments of muscle fibers. This signals tropomyosin to move out of the myosin binding sites on actin.

66
Q

Muscle Contraction: Powerstroke

A

Energized myosin heads, with an attached ADP molecule and phosphate group, bind to the open myosin binding sites on actin. This forms the actin-myosin cross-bridge.

After the cross-bridge forms, the myosin head rotates towards the center of the sarcomere. As it rotates, the myosin releases its ADP and phosphate.

This action slides the thin actin past the thick filament, creating the power stroke.

67
Q

Muscle Contraction: Actin-Myosin Detachment

A

After the power stroke, the actin-myosin cross-bridge remains intact until an ATP molecule binds to the myosin head. After ATP attaches to myosin, the myosin detaches from actin.
