Q

explain the main differences between the male and female skeleton

A

male:
- heavier and larger pelvis
- narrow, deep, and more funnel shaped

female:

  • wider and flare shape
  • increased inward slant of the hips and knees

16
Q

what are the functions of articulations (joints)?

A

Functional junction between 2 or more bones

- AKA connects 2 or more bones together using ligaments

17
Q

what are the classifications of joints?

A

1) synarthroses- immovable joints
2) Amphiarthroses- slightly moveable
3) diarthroses (synovial) - freely movable

18
Q

what are the 6 varieties of synovial joints?

A

1) ball & socket (multuple planes of motion)
2) hinge (move in one plane of motion)
3) pivot (rotation in one plane of motion ex: ulnar)
4) saddle (barely any movement ex: thumb)
5) gliding (gliding on top of one another ex: carpals)
6) condyloid (moving in one direction ex: knee joint)

19
Q

how many muscles are in the human body?

A

around 600

20
Q

what is the principle of leverage?

A

Skeletal muscle power is nothing without lever action. The bone acts as a rigid bar, the joint is the fulcrum, and the muscle applies the force

21
Q

what is the principle of optimum joint angle?

A

when the joint is in a weird position or stretched, it becomes weaker = more prone to injury. there is a optimum angle in which the joint can produce the most force

22
Q

what are the divisions of the nervous system?

A
  • central nervous system

- peripheral nervous system

23
Q

what is the difference between sensory (afferent) and motor (efferent) nerves?

A

sensory = posterior branches. transmit information from sensory receptors in the kin, tendons, ligaments, and muscles to the CNS (brain & spinal cord)

motor = transmit control signals to the muscles from the CNS

24
Q

what is the difference between voluntary (somatic) and involuntary (visceral) nerves?

A

somatic = innervates a series of skeletal muscles and provides sensory input from the skin, fascia, muscles, and joints

visceral = part of the autonomic nervous system

25
Q

explain the difference between the sympathetic and parasympathetic nervous system

A

sympathetic = nervous actions and involuntary and done when the body is in a stressful situation (fight or flight)

parasympathetic = voluntary and body is relaxed

26
Q

what is a nervous plexus?

A

branching network on intersecting nerves

27
Q

what is a dermatome?

A

area of skin in which sensory nerves serve from a single spinal nerve root

28
Q

what is a myotome?

A

selected motions innervated predominantly by a single nerve root

29
Q

what is Wolff’s law?

A

bones and soft tissues respond to the physical demands that are placed on them, causing the formation of collagen to remodel or realign along the lines of stress, and thereby promoting healthy joint biomechanics
