Warm up 5/5

Warm up 5/5

• Tomorrow we will meet in Rm 151
• 2nd science room from front of the school
• Take the histology lab and turn to page 3.
• Come to the front and get 1 microslide viewer and
  one microslide strip. (Groups of 2)
• Look at 3 different slides. Draw pictures of the
  slides in the field of views provided on page 3
  of the lab.
• Answer questions 10-14
• Must clean up by 200 pm

2
MUSCULAR SYSTEM II

• PP. 920-922

3
MUSCLE STRUCTURE CONT.

• Ligaments connect joints
• Tendons connect muscle to bone
• When the muscle moves, the bones move, and the
  joint bends

4
(No Transcript)
5
MUSCULAR MOVEMENT

• Muscles arranged in opposing pairs and while one
  relaxes the other contracts
• flexor contraction bends the joint
• extensor contraction straightens the
  joint

6
MUSCLE FATIGUE

• The inability to contract the muscle due to the
  lack of ATP

7
SKELETAL SYSTEMfor dummies
RED Important BLACK Write Down BLUE Dont
write down

• pp 911-916

8
FUNCTION

• Bones support muscles and organs
• produce red and white blood cells
• gives shape and structure to the body
• protects internal organs
• store minerals

SKELETON

• Axial the skull, face, vertebral column, and rib
  cage.
• Appendicular the arms and legs, pelvis, scapula,
  collar bone, etc
• bones and their associated tissues (cartilage and
  ligaments) make up the skeletal system to support
  the body

11
BONE STRUCTURE

• porous and made of proteins and minerals
• osteocytes cells that make bone
• bone marrow soft bone tissue that produces
  platelets and blood cells

12
(No Transcript)
13
BONE DEVELOPMENT

• develop from cartilage (tough flexible connective
  tissue)
• ossification hardening of bone cartilage
• elongation at the end of bones

14
JOINTS

• place where two bones meet

15

• Fixed no movement between bones (ex. skull).
• Semimovable limited movement (i.e. rib cage and
  vertebrae)
• Movable
• 1. hinge knee and knuckle
• 2. pivot skull joins the vertebral
  column
• 3. ball-and-socket hip
• 4. gliding wrist and ankle (slide over
  one
• another)

16
JOINT STRUCTURE

• cartilage between joints for cushion
• ligaments connect joints (bone to bone)

17

• Quiz Tomorrow
• P 922 9, 10 (Due Tues)
• Look at p 929 7. Define parts of picture 1-4.
• Is this muscle elongated or contracted? (Due
  Tues)
• Problems p 922 5-7 Due Wednesday
• Physiology Study Guide Due Thursday
• Histology Lab (Due Friday)
• Exam Friday Intervention Wed Thur
