Q

Voluntary muscle

A

Under conscious control. Skeletal muscles must work in pairs: the muscle that executes a given move it is the prime mover, whereas the muscle that produces the opposite movement is the antagonist. Other muscles known as synergist may work in cooperation with the prime mover

25
Meiosis takes place
Sell the business takes place in gonands and ovaries and testes.
26
Meiosis process
Chromosome number is reduced from 46 to 23 so when the egg and the spermine night and fertilization the cycle will have the correct number of chromosomes.
27
What is the largest organ of the body
The skin
28
Two layers of the skin
Epidermis the outer most protective layer of dead here tonight epithelial cells in the dermis underlying layer of the connective tissue
29
Rears about the epidermis from outer layer to inner layer
Stratum corneum, Stratum lucidum, stratum granulosum, and inner most Stratum germinativum
30
Where does mitosis occurs
Epidermis
31
What do epidermal cells contain
Protein pigment called melanin which protects against radiation from the sun
32
inner layer of the skin
Dermis composed of fibrous connective tissue with blood vessels sensory nerve endings hair follicles and grands
33
Two types of sweat glands
Eccrine regulate body temperature by releasing a watery secretion that evaporates on the surface of the skin. Applicants creation mainly in the armpits in groin area.
34
Sebaceous glands
Release and oily secretion receiver do the hair follicles that lubricates the skin and prevents drying.
35
Oil
Produced by Halycon secretion and which host cells of the gland are part of secretion
36
What are the appendages of the skin
Hair and nails both are composed of Keratin
37
Body framework consists of
Bone cartilage ligaments and joints
38
Functions of the skeletal system include
Support movement blood cell formation protection of internal organs the detoxification provision for muscle attachment and mineral storage
39
How are individual bones classified?
Shape | Including long short flat irregular and seamoid bones
40
Long bone has
Irregular epiphysis at each end, composed mainly of spongy bone, and a shaft or diaphysis, composed mainly of compact bone.
41
What cells form compact bone?
Osteoblasts eventually become osteocytes once they stop dividing
42
Axial skeleton face and skull
28 bones of the skull 14 facial bones and 14 bones of the cranium. Facial bones have 2 nasal bones 2 maxillary bones 2 zygomatic bone one mandible two palatine bones one vomer bone two lacrimal bones and two inferior nasal cavities. Bones of the cranium are the single occipital frontal ethmoid and sphenoid and the paired Parietal Temporel And ossicles of ear (malleus incus and stapes)
43
Axial skeleton a vertebral column
33 bones vertebral column | Seven cervical vertebrae, 12 thoracic vertebrae, five lumbar vertebrae, five sacral vertebrae, and coccygeal vertebrae.
44
Axial skeleton bones of thorax
Sternum and 12 pairs of ribs
45
Appendicular skeleton includes
The girdles and the limbs
46
Upper portion of the appendicular skeleton
Pectoral or shoulder girdle, clavicle and scapula, and upper extremity.
47
Appendicular skeleton bones of the arm
Humerous, radius, Anna, carpals or responds, metacarpals or bones of the hands, and phalanges or bones of the fingers.
48
Appendicular skeleton lower portion
Pelvic girdle or on coxae
49
Appendicular skeleton os coxae
Fused illum, ischium, pubis.
50
Appendicular skeleton bones of lower extremity
Femur, tibia and fibula, tarsals, metatarsals, phalanges
51
Muscle contraction results from
Siding together from actin and myosin filaments with the new muscle cell or fiber
52
Sacromeres
Each muscle consist of myofibrils which in turn are made up of still small units
53
What must be present for muscles cells to contract
Calcium and adenosine triphosphate ATP
54
Flexors and extensors
Flexes reduce the angle at the joint where as extensors increase the angle
55
Abductors and adductors
Abductor draw a lim away from the midline. Where as abductors return the limb back toward the body
56
Nervous system consists of
Brain, spinal cord, and nerves
57
Nervous system enables us to
Think reason remember carry out other abstract activities
58
Nervous system works closely with what glands
Endocrine gland correlating and integrating that he functions such as digestion and reproduction
59
Main parts of a neuron
Cell body axon dendrites
60
Sagittal section
Cut along the median plane
61
Nervous system can be divided into
Central nervous system and peripheral nervous system
62
PNS transmit information
To and from the CNS
63
Sensory and friend her and transmit
Nerve pulses toward the CNS
64
Motor efferent neurons transmit nerve impulses
Away from the CNS towards the effector organs and Digestive organs
65
Major parts of the brain are
Cerebrum which is associated with movement and sensory input. Cerebellum which is responsible for muscular coordination. In the mid Dula which controls vital functions such as respiration and heart rate.
66
The spinal cord is approximately how many inches long
18
67
The spinal cord extends from
The base of the skull or Freeman magnum to the first or second lumbar vertebrae
68
How many spinal thirds exist in the spinal cord
31 pairs
69
Simple spinal reflexes are
In which the nerve pulses travel through the spinal cord only and do not reach the brain
