Semester 1 Midterm Flashcards
What is the function of the skeletal system?
Holds the body up and helps the muscle move
What is the function of the nervous system?
Controls senses, responses, and thought
What is the integumentary system and what is its function?
the physical barrier between the external environment and the internal environment that serves to protect and maintain. (skin, hair, nails, exocrine glands)
What is the anatomical position?
- Body Up Right
- Arms by side
- Palms Forward
- Toes Forward
- Always assumed
Gluteal
Buttocks/ butt
Tarsal
ankles
Thick Skin
5 Layers (only on palms and soles of feet)
Contains S. Lucidum
What is the Muscular System and its function?
Attaches to skeleton to move the body.
Abdominal
Stomach
Nasal
nose
Oral
Mouth
Acromial
Shoulder
Cervical
Neck
Orbital
eyes
Coxal
Hip
Dermis
Deep (second) layer of the skin
What are the two types of Cutaneous Glands?
Sebaceous Glands & Sudoriferous Glands
Axillary
Underarm/armpit
patellar
front of knee
Digital
Fingers
pelvic
Front between hip bones
The study of the shape and structure of the body
Anatomy
Brachial
Arm (shoulder to elbow)
Dermis layers
Papillary layer and reticular layer
Femoral
Thigh
Buccal
Cheek
receptor
detects change
The study of how the body and its parts work or function
Physiology
Calcaneal
heal of the foot
Carpal
Wrist
Function of dermis
Gives the skin its flexibility and strength; binds dermis to underlying tissue
Cephalic
head
negative feedback
the output reduces the original effect of the stimulus
Carotene
The yellow/orange pigment of the skin
What is homeostasis ?
The ability of the body to maintain a relatively stable/constant internal environment, regardless of environmental changes.
What are the levels of organization?
Chemical, tissue, organ, organ system, organism
What’s the Mnemonic for the layers of the skin?
C - alifornians (Stratum Corneum)
L - ove (Stratum Lucidum) only in thick skin
G - ood (Stratum Granulosum)
S - andy (Stratum Spinosum)
B - eaches (Stratum Basale)
What is an eccrine sweat gland?
produce sweat in response to temp, not stinky
Effector
It returns variable back to homeostasis
What is the epidermis?
The outer layer of the two main layers of skin
sacral
back between hip bones/ gluteal cleavage.
Positive feedback
output that enhances the original stimulus
Hemoglobin
Pigments in red blood cells; adds reddish pinkish hue to skin
scapular
shoulder blades
What is Sebum?
Sebum is an oily and waxy substance found in the sebaceous gland.
Hypodermis
Deep to the dermis
Thin Skin
4 layers (everywhere else)
Contains S. Corneum, S. Granulosum, S. Spinosum, S. Basale
sternal
Breast bone
What are the survival needs?
- nutrients
- oxygen
- water
- normal body temp
- atmospheric body pressure
umbilical
belly button
What is the last layer of the skin?
The Stratum Basale
What is the apocrine sweat gland?
sweat that contains proteins and fatty acids, stinky
Melanin
Responsible for tanning of the skin when exposed to sunlight
What are the 4 cavities and what do they hold?
cranial cavity, thoracic cavity, abdomino pelvic, spinal cavity. The cranial activity holds the right frontal lobe and, cerebellum. The thoracic cavity holds the pericardium and the left lung. The abdomino pelvic holds the gall bladder, stomach, jejunum, ureters, renal capsule, urinary bladder, and liver.The spinal cord holds the spinal cord
mucus membrane
lines body cavities open to the body exterior
most secrete mucus
respiratory tract
urinary t reproductive tract
What are the 3 body planes?
The 3 body planes are sagittal section, transverse section, and a frontal section. A sagittal section divides the body into left and right. A tranverse section divides the body into superior and inferior. The frontal section divides the body into anterior and posterior.
