Q

Venous pooling

A

A term used to describe the accumulation of blood in the extremities due to slow blood flow through the veins (venous return) or backflow (Goodman, 2015; Reid et al., 2014). When the venous return is reduced as a result of damage to the veins, such as the one-way valves not working, swelling in the extremities may accumulate and the veins of the leg become more visible

43
Q

Arthrokinematics

A

Joint Movement. The description of joint surface movement; consists of three major types: roll, slide, and spin.

44
Q

Rolling Joints

A

A rolling joint movement, one joint rolls across the surface of another much like the tire of a bicycle rolls on the street.

45
Q

Synovial Joints

A

Most common joints associated with human movement. They comprise approximately 80% of all the joints in the body and have the greatest capacity for motion.

46
Q

Synovial joints produce synovial fluid

A

Synovial fluid resembles egg whites and works much like engine oil. It is secreted within the joint capsule from the synovial membrane and is essential for lubricating the joint surfaces to reduce excessive wear and to provide nutrition to the joint structures within the synovial capsule

47
Q

Synovial Joints

A

Gliding, condyloid, hinge, saddle, pivot, and ball-and-socket joints.

48
Q

Non-Axial Joint has simple movements of all joints

A

It moves either back and forth or side to side.

49
Q

Condyloid joints

A

Because the condyle of one bone fits into the elliptical cavity of another bone to form the joint

50
Q

Nonsynovial Joints

A

They have no joint capsule, fibrous connective tissue, or cartilage in the uniting structure.

51
Q

Ligaments

A

Fibrous tissues that connect bone to bone provide static + dynamic stability, as well as sensory input to the nervous system that aids proprioception

52
Q

Ligaments 2

A

Primarily made up of collagen with varying amounts of a second protein called elastin.

53
Q

Collagen

A

A protein found in connective tissue, muscles, and skin that provides strength and structure. It is the most abundant protein in the human body.

54
Q

Elastin

A

A protein that provides elasticity to skin, tendons, ligaments, and other structures.

55
Q

Muscular System

A

Links the nervous and skeletal systems and is responsible for generating the forces that move the human body.

56
Q

3 types of muscles

A

Skeletal, cardiac, + smooth

57
Q

Cardiac Muscle

A

Makes up the heart, smooth muscle + tissues of internal organs

58
Q

Skeletal Muscle

A

Made up of individual muscle fibers held together by connective tissues. Primary functions are to contract + produce movement, support the skeletal system, + assist with the homeostasis of the body by producing heat.

59
Q

Fascia

A

Connective tissue that surrounds muscles and bones.

60
Q

Skeletal muscle

A

The type of muscle tissue that connects to bones and generates the forces that create movement.

61
Q

Epimysium

A

The inner layer of fascia that directly surrounds an entire muscle is commonly referred to as the “deep fascia.”

62
Q

Fascicles

A

Largest bundles of fibers within a muscle. Fascicles are surrounded by perimysium.

63
Q

Perimysium

A

The connective tissue surrounding a muscle fascicle.

64
Q

Endomysium

A

Connective tissue that wraps around individual muscle fibers within a fascicle.

65
Q

Tendons Vs. Ligaments

A

Tendons connect muscles to bones. Commonly discussed tendons include the Achilles tendon at the ankle and the patellar tendon of the knee. When a tendon is overstretched or torn, this is known as a strain.

Ligaments connect bones to bones. A commonly discussed ligament is the anterior cruciate ligament of the knee that connects the tibia to the femur. When a ligament is overstretched or torn, it is known as a sprain.

66
Q

Muscle fibers + contractile elements

A

Within the endomysium of the fascicles, individual muscle fibers are themselves encased by a plasma membrane known as the sarcolemma

67
Q

Glycogen

A

Glucose is deposited and stored in bodily tissues, such as the liver and muscle cells; the storage form of carbohydrates.

68
Q

Myoglobin

A

Protein-based molecule that carries oxygen molecules into the muscles.

69
Q

Myofibrils

A

The contractile components of a muscle cell; the myofilaments (actin and myosin) are contained within a myofibril.

70
Q

Myofilaments

A

The filaments of a myofibril; include actin and myosin.

71
Q

Actin

A

The thin, stringlike, myofilament acts along with myosin to produce a muscular contraction.

72
Q

Myosin

A

The thick myofilament acts along with actin to produce a muscular contraction.

73
Q

Sarcomere

A

The structural unit of a myofibril is composed of actin and myosin filaments between two Z-lines.

74
Q

Z-line

A

A

The specialized site where the nervous system communicates directly with muscle fibers.

78
Q

Neural Activation

A

The nervous system’s signal tells a muscle to contract.

79
Q

Action Potential

A

A nerve impulse that is relayed from the central nervous system through the peripheral nervous system, + into the muscle across the neuromuscular junction.

80
Q

Neurotransmitters

A

Chemical messengers that cross the synapse between neuron + muscle, released into the gap

81
Q

Acetylcholine (ACh)

A

A neurotransmitter used by the neuromuscular system. A neurotransmitter that helps the action potential cross the synapse into the muscle, which initiates the steps in a muscle contraction.

82
Q

Action Potential

A

A nerve impulse that is relayed from the central nervous system, through the peripheral nervous system, + into the muscle across the neuromuscular junction.

83
Q

Sliding filament theory

A

Further describes how myosin (thick) and actin (thin) filaments slide past one another to produce a muscle contraction, shortening the entire length of the sarcomere and, concurrently, the muscle as a whole
